4 | Bright underlying galaxy, weak OIII5007/4959 in emission, XID uncertain |
22 | Outburst magnitude given |
27 | XID from appearance on DSS |
30 | Optical spectrum resembles that of normal galaxy without emission lines, |
30 | enhanced flux at wavelengths shortward the Ca-break, much too high X-ray |
30 | luminosity for a normal galaxy, no X-ray extent and no obvious cluster |
30 | on DSS2, XID as weak BL Lac or XTG (like RBS1135(=IC3599) or RBS1583) |
30 | possible, HR1 more suggestive of the former, since the latter typically |
30 | have soft spectra |
62 | Sy1 in cluster ACO S 0047 |
64 | XID uncertain due to relatively large CaII break, X-ray source might be a |
64 | NELG at RA=00 27 13.7, DE=-27 08 56 with z=0.062. |
65 | One redshift measured of galaxy at specified optical position |
75 | A spectrum of only one galaxy was obtained, XID tentative, no X-ray extent |
75 | in RASS, XID as BL Lac also possible |
88 | WPVS 07 can also be regarded as X-ray transient galaxy. Grupe discovered |
88 | the transient nature of the X-ray activity of this Sy-galaxy |
96 | L. Wisotzki (priv. comm.) |
97 | XID as cluster not excluded, although RASS-data show no X-ray extent |
114 | The NED gives an id as normal galaxy referencing to the LCRS (Shectman et |
114 | al., 1996, Cat. <VII/203), inspection of the spectrum made available by |
114 | D. Tucker shows weak emission lines suggestive of an AGN nature |
123 | The star visible on the DSS at the given optical position is an unresolved |
123 | (apparent) binary, the fainter component is a dMe, the likely X-ray |
123 | source, the brighter a G star |
126 | Only one redshift taken, XID tentatively |
138 | XID from appearance on DSS |
145 | Coordinates and redshift for the (cD;E+3 pec ) galaxy ESO 541- G 013 given |
150 | Redshift due to Wisotzki (priv. comm.), DSS shows nearby, probably |
150 | interacting companion galaxies |
162 | Wisotzki, priv. comm. |
172 | Mean of two redshifts given |
178 | Redshift measured for galaxy at RA=01 18 11.2, DE=-26 58 12 |
181 | Two redshifts measured, $z=0.0508$ for RA=01 20 58.5, DE=-13 51 00, and |
181 | z=0.0488 for the galaxy at RA=01 20 52.0, DE=-13 51 16 |
216 | Sy-galaxy in interacting group |
230 | Sy-galaxy in interaction with NELG at RA=01 40 28.8, DE=-66 29 39 |
238 | The redshift given is the mean of three, RA/DE/Mag for the galaxy nearest |
238 | the X-ray position |
243 | Tentative XID based on visual inspection of DSS |
256 | XID with GSC 01757-01936, a K4 star is also possible |
295 | Remillard, priv. comm. |
311 | XID with G 94-B5B (white dwarf) possible from positional coincidence, but |
311 | hard X-ray spectrum is suggestive of the XID as given |
312 | Mean of two redshifts given |
316 | A Sy galaxy and a cluster of galaxies (Abell S0261) as possible |
316 | counterparts from NED correlation, no X-ray extent measured |
321 | SIMBAD lists only the F3IV/V star, Fleming identified the WD as companion |
321 | and XID |
325 | Mean of two redshifts given |
378 | Detection of 40 photons in 67 sec during the RASS, the source was not |
378 | detected during a PSPC-survey repair pointing and a later HRI- pointing, |
378 | tentative identification as X-ray transient |
380 | Mean of two redshifts given |
387 | Redshift (col.~13) of galaxy at optical position (cols. 2-3) given, |
387 | the NED lists a second galaxy with redshift 0.2613 at RA=03 07 01.4, |
387 | DE=-28 41 21 |
397 | Wisotzki, priv. comm. |
408 | redshift changed from 0.703 to 0.0701 (a typo discovered by A. Edge) |
419 | Our XID, based on Maza et al. (1989ApJS...69..349M), differs from that |
419 | given by Thomas et al. (1998, Cat. <J/A+A/335/467>), who identify |
419 | ESO 301-G13 (Sy1, z=0.064) at a distance of 67 arcsec as optical |
419 | counterpart |
431 | Abell 3128, the same counterpart to RBS0432 |
432 | Abell 3128b, the same counterpart to RBS0431 |
436 | The group is overshone by two rather bright stars, the optical position |
436 | given is that of a Sy1.9 galaxy |
441 | SIMBAD also gives a classification as [MPP88] 0331-373, a Sy1 galaxy at the |
441 | same optical position |
445 | Low S/N spectrum which does not allow to determine the subtype and the |
445 | redshift |
447 | Two redshifts taken near the center of the X-ray emission |
453 | L. Wisotzki (priv. comm.) |
456 | The central dominant galaxy of the cluster is a Sy2 galaxy, X-ray emission |
456 | is extended, therefore likely XID as cluster, not as AGN |
485 | The NED lists only a single galaxy, not a group or cluster. X-ray extent |
485 | measured in RASS-data, XID as cluster likely, with the galaxy as likely |
485 | member |
496 | XID with GJ 157B (Sp M2) also possible) |
507 | NED lists also Abell 3223 at the X-ray position with the same redshift. The |
507 | Seyfert galaxy probably belongs to the cluster, no significant X-ray |
507 | extent |
526 | The identification spectrum is blue und featureless, indicative of a BL Lac |
526 | nature, but rather faint due to the faintness of the source. The galaxy |
526 | north of the BL Lac candidate has a weak Seyfert nucleus and a |
526 | contribution to the observed X-ray flux cannot be excluded. |
531 | XID uncertain. The optical image shows a galaxy, whose spectrum has a |
531 | strong O[II]3727 emission line, weak Balmer H{beta} emission and a flat |
531 | blue continuum shortward of 3700{AA} (rest wavelength). The X-ray image |
531 | is slightly extended. |
552 | XID not fully convincing because of large distance between X-ray and |
552 | optical positions, a star-like object within the X-ray error circle at |
552 | RA=04 35 14.4, DE=-46 15 33 has not yet been observed but might be the |
552 | true counterpart |
571 | XID as GJ 174.1B, a M0.5 star (V=12.5mag), also possible |
599 | Optical coordinates wrong in SIMBAD, used are the original coordinates by |
599 | Thomas et al., 1998, Cat. <J/A+A/335/467> |
607 | Sy1 galaxy in group or cluster, three redshifts taken |
632 | XID as 4U 0513-40, a LMXB possible, but X-ray source extended |
656 | ID based on inspection of DSS |
730 | High proper motion star, the X-ray source therefore lies in a blank field |
730 | on POSS plates, recent Schmidt plates show the star within the X-ray error |
730 | circle (D. Engels, priv. comm.) |
735 | Bade, priv. comm. |
737 | Bade, priv. comm. |
745 | Sy-galaxy in cluster, X-ray source extended, XID therefore cluster |
780 | Bade, priv. comm. |
797 | XID changed with respect to Paper I (A. Edge, priv. comm.) |
804 | The identification spectrum has a strong galaxy component, DSS shows more |
804 | faint galaxies, XID as cluster possible, although no significant X-ray |
804 | extent was detected in the RASS-data |
844 | The identification spectrum has a strong galaxy component, DSS shows more |
844 | faint galaxies, XID as cluster possible, although no significant X-ray |
844 | extent was detected in the RASS-data |
867 | Bade, priv. comm. |
871 | X-ray source is extended, it is most likely a blend of two pointlike |
871 | sources, the bright star HD,90748 (Sp F8) and the Sy-galaxy; the Sy-galaxy |
871 | has a companion at RA=10 29 03.4, DE=+27 27 40 with the same redshift |
900 | Bade, priv. comm. |
903 | Bade, priv. comm. |
913 | A contribution to the X-ray flux from the nearby Sy2 galaxy at |
913 | RA=10 51 51.2, DE=+21 37 59 ($z=0.0529) is possible |
915 | Mean of two redshifts given |
969 | ID based on inspection of DSS |
973 | Alternative XID possible: SZ Crt, Sp K4/K5V(By Dra), |

989 | Bade, priv. comm. |
1015 | Mean of three redshifts given |
1020 | The dominant galaxy at RA=11 41 24.1, DE=--12 16 39 observed by us has |

1267 | Mean of two redshifts given, a third nearby galaxy RA=13 26 17.5, |
1267 | DE=+12 29 18 does not belong to the cluster (z=0.1478) |
1276 | The identification spectrum is that of a faint normal galaxy at z=0.15. |
1276 | The X-ray source is not obviously extended (XID not cluster), the extreme |
1276 | softness of the X-ray spectrum suggests a possible XID as X-ray transient |
1276 | galaxy (accretion event onto a SMBH) |
1300 | The nearby companion galaxy at RA=13 40 38.1, DE=+40 36 28 has the |
1300 | same redshift |
1302 | BLL and nearby cluster ABELL 1774 have almost same redshift, no RASS X-ray |
1302 | extent, XID as BLL likely |
1307 | Bade, priv. comm. New observation: type now Sy1 (instead of Sy), redshift |
1307 | now 0.171 (instead of 0.176) |
1310 | Bade, priv. comm. |
1317 | Miller, priv. comm. |
1319 | IC 4329A + ABELL 3574, negligible X-ray extent, XID as AGN likely |
1321 | UGC 08738 is an absorption line galaxy (Thorstensen et al., 1995, |
1321 | Cat. <J/AJ/109/2368>), a possible member of Abell 1800, the X-ray source |
1321 | does not show an obvious sign of an extent, the X-ray luminosity is too |
1321 | high to be compatible with a normal absorption line galaxy, an XID as weak |
1321 | BL Lac could be possible |
1322 | PMN J1350+0940 possibly in cluster, X-ray extended |
1324 | XID (based on NED correlation) is uncertain due to large separation between |
1324 | optical and X-ray position and the missing X-ray extent |
1327 | Featureless blue discovery spectrum with low S/N; FIRST J135326.1+362049, |
1327 | a QSO with z=0.284, is offset by 80 arcsec from the X-ray position, |
1327 | probably too far away |
1345 | Miller, priv. comm. |
1353 | Nearby stars at RA=14 09 18.7, DE=+13 52 59 (Sp F) and |
1353 | RA=14 09 18.1, DE=+13 52 38 (Sp K) not the XID |
1372 | The Seyfert-galaxy resides in an interacting group |
1374 | Miller, priv. comm. |
1376 | Greiner, priv. comm. |
1385 | Two redshifts were taken of galaxies at RA=14 23 51.6, DE=+40 15 32 |
1385 | (z=0.0829) and RA=14 23 51.4, DE=+40 14 16 (z=0.0817) |
1402 | Bade, priv. comm. |
1423 | An optically bright, extreme blue Sy1 galaxy at RA=14 44 14.7, DE=+06 33 07 |
1423 | (V=16.2, z=0.208) might also contribute to the X-ray emission |
1428 | The discovery spectrum is that of a normal absorption line galaxy with weak |
1428 | H{alpha} emission; no other obvious possible optical counterpart nearby; |
1428 | the extreme softness of the X-ray spectrum is suggestive of an X-ray |
1428 | transient galaxy |
1429 | Bade et al. (1998A&AS..127..145B) identify this source as an AGN. This XID |
1429 | is probably, we took two spectra of absorption line galaxies with almost |
1429 | same redshift, suggestive of an XID as cluster of galaxies |
1433 | A nearby NELG (RA=14 48 26.7, DE=+35 59 53) with same redshift, interaction |
1444 | Optical position given in NED probably wrong, no object on DSS at given |
1444 | position |
1475 | Although the optical spectrum is suggestive of a HII galaxy, the occurrence |
1475 | of an X-ray outburst during the RASS makes the presence of a SMBH likely |
1475 | (Komossa & Bade, 1999A&A...343..775K) |
1500 | Sy1 in ABELL 2072, X-ray emission point-like, probably mainly from the |
1500 | Sy-galaxy |
1504 | A contribution from HD 139777, a V=6.6 star (G0IV-V+.) at |
1504 | RA=15 29 11.1, DE+80 26 54, appears to be likely |
1508 | Strong galaxy contribution to the discovery spectrum, companion galaxy |
1508 | (RA=15 32 4.1, DE=+30 15 49) at same redshift, XID as cluster unlikely |
1508 | due to missing X-ray extent but not completely excluded |
1509 | Classified as LINER in Paper I. A. Edge (priv. comm.) confirms its cluster |
1509 | nature with the optical line emission originating from the cooling flow |
1512 | Possible contribution to the X-ray flux from a nearby dMe star |
1512 | (RA=15 33 44.1, DE=+69 00 55) |
1521 | Bade, priv. comm. |
1526 | Two extragalactic objects are found among several faint foreground stars, |
1526 | which are most likely not the counterparts of the X-ray source: the first |
1526 | is the NELG galaxy at the position and with the redshift as given in the |
1526 | table, the second is an absorption line galaxy at |
1526 | RA=15 42 36.6, DE=+58 11 52 with a redshift of z=0.23. This observation |
1526 | might be suggestive of a galaxy cluster, the X-ray source, however, is not |
1526 | obviously extended. |
1533 | The NED lists at almost the same position an unspecified AGN (no type, |
1533 | no redshift) |
1540 | A Sy2 galaxy belonging to the cluster lies at RA=15 56 14.4, DE=+66 20 56; |
1540 | the X-ray source is clearly extended, XID as cluster |
1547 | AG Dra correctly identified as symbiotic binary |
1551 | XID uncertain due to the faintness of the star |
1560 | The nearby radio source FIRST J160714.6+340229 of unknown nature could also |
1560 | be the X-ray source |
1583 | The discovery spectrum shows features of a normal absorption line galaxy; |
1583 | Grupe, Thomas & Leighly (1999A&A...350L..31G) propose an XTG-nature of |
1583 | this object caused by an accretion event onto a SMBH |
1623 | NED Sy2, SIMBAD Sy1 |
1636 | The galaxy at RA=17 18 12.1, DE=+56 39 56 is a Sy1 galaxy. X-ray emission |
1636 | extended, XID as cluster |
1680 | A spectrum of the object at RA=20 31 51.2, DE=-40 36 53.7, was taken. |
1680 | It is a faint G or K star without further sign of X-ray activity, not |
1680 | regarded as XID; slight X-ray extent observed in RASS, cluster candidate, |
1680 | privately confirmed by H. Bohringer and J. Retzlaff (REFLEX cluster |
1680 | survey) |
1691 | Two redshifts taken, the first of the galaxy with coordinates as given in |
1691 | the table (z=0.098), the second at RA=20 41 46.4, DE=-37 36 21 (z=0.109). |
1697 | Spectra were taken of the objects at optical position |
1697 | (RA, DE) (20 45 12.8, -40 48 54), (20 45 11.2, -40 48 33), |
1697 | (20 45 16.0, -40 48 53), (20 45 14.5, -40 48 25.9). All objects are rather |
1697 | faint F or G stars, not the XID. Possible XID with GSC 07967-01203 at |
1697 | RA=20 45 11.5, DE=-40 49 57, a V=10.7mag star |
1705 | SIMBAD lists a star of spectral type F8, the soft X-ray spectrum suggests |
1705 | an undetected white dwarf as XID |
1719 | Three redshifts measured |
1728 | Alternative XID as GJ 818.1 or GJ 9719 |
1737 | IR-excess, ID correct/unique? |
1743 | Three redshifts measured |
1748 | Two redshifts measured |
1756 | Sy-galaxy interacting with nearby NELG at |
1756 | RA=21 32 02.8, DE=-33 42 01 (z=0.0293) |
1779 | Possible contribution to the X-ray flux from a nearby Sy-galaxy (z=0.211) |
1779 | at RA=21 46 27.2, DE=-47 48 25 |
1818 | optical position changed to 22 04 17.5, -42 58 14, according to |
1818 | Beuermann et al., 1999A&A...347...47B. |
1831 | Two redshifts measured |
1842 | A background Sy-galaxy (z=0.2379) lies in a foreground cluster of galaxies |
1842 | (two redshifts, z=0.136), X-ray emission extended, XID as cluster |
1846 | Grupe (priv. comm.) pointed to the transient nature of the source. Grupe |
1846 | discovered the transient nature of the X-ray activity of this Sy-galaxy |
1861 | Two redshifts measured of galaxies at (22 25 51.4, -06 35 52) and |
1861 | (22 25 50.5, -06 36 05) |
1864 | Not a completely convincing XID, the (noisy) spectrum of the faint galaxy |
1864 | at the given optical position does not show any obvious hallmark of an |
1864 | X-ray source, the soft X-ray colour makes this source similar to other |
1864 | XTGs, XID as (weak, hidden) BLL possible; the second object near the X-ray |
1864 | position at RA=22 28 00.3, DE=-41 57 07 is a faint K star, definitely not |
1864 | the X-ray source |
1888 | SIMBAD cites the XID given in our Paper I incorrectly |
1929 | XID rests on one measured redshift of a galaxy at the given optical |
1929 | position, the X-ray extent measured, and the galaxy pair listed in the NED |
1929 | at (23 00 59.9, +06 45 02) at z=0.0402. |
1947 | Spectra of objects at (23 07 26.3, -17 56 24), a faint K star, and at |
1947 | (23 07 20.2, -17 56 28) an F star (=GSC 06398-00470, V=11.0) were taken. |
1947 | These are not regarded as XID, due to their faintness or their large |
1947 | distance from the X-ray position |
1972 | No cluster is catalogued, no observation by us. RASS X-ray extent and |
1972 | inspection of DSS showing several galaxies around suggest the XID |
1985 | Two redshifts taken of galaxies at (23 19 40.6, -73 13 36) and |
1985 | (23 19 37.9, -73 14 44) |
1991 | Possible/likely contribution from the nearby cluster ABELL 3995, |
1991 | RA=23 21 35.3, DE=-69 41 33, z=0.1864, V=17.3/10, RASS source not extended |
2018 | Possible contribution to RASS X-ray flux from CCDM J23319+1956C and D |
2023 | The NED cites wrong coordinates for CTS,69 when compared with the original |
2023 | reference; CTS,69 is somewhat off the X-ray position, the celestial body |
2023 | right at the nominal position of the X-ray source is an absorption line |
2023 | galaxy with z=0.0963, not the XID |
2035 | Wrong classification in NED (normal galaxy) |
2042 | Three redshifts taken |
2057 | The cluster is centred 2 arcmin away from the X-ray position, the X-ray |
2057 | source is not obviously extended, regard the Sy as XID |
