#-- J/A+AS/58/39 1412 MHz catalogue of Westerbork survey. II (Windhorst+, 1984)
#--------------------------------------------------------------------------
#---Table: J/A+AS/58/39/notes.dat Individual notes (119 records)
# WSTB A6 --- Westerbork designation
# Note A73 --- Text of the Note (1)
#Note (1): Individual notes are given for optical objects that could not be
# adequately described in notes 5-8. Notes are also given for the 25
# extended or complex radio sources for which the identification was not
# straightforward. For this latter subsample we classify the suggested
# identification as solid, very likely, likely or possible. The 21cm
# information is taken from Paper I, (Windhorst et al., Cat.
# <J/A+AS/58/1>) where contours of extended and complex radio sources
# are given, in which the positions of the optical objects from the
# current paper are marked with crosses. The surface brightness of the
# radio sources was noted from these contour plots or from a comparison
# between the contour plots of the high resolution and the low
# resolution 21cm maps of Paper I and the 50cm maps of Windhorst and
# Oppe (1984; Paper IV, submitted). For extended sources the western-
# and eastern-most components are referred to as A and B respectively,
# while any detectable central component is called C. All 50cm radio
# information (including spectral index {alpha}=-logS_v_/logv) is taken
# from Paper IV. For a few sources that were asymmetrically resolved at
# 21cm a better position was obtained at 50cm, which in a few doubtful
# cases clarified the situation. All additional optical information
# (photometry, spectra) is taken from Paper III (Kron et al.,
# 1985A&A...146...38K), unless stated otherwise.

52W005|Very red faint galaxy in low surface brightness radio source. Object
52W005|closer to 50cm position. Likely identification.
52W013|cD galaxy in Zwicky cluster 1305.4+2941, which is also detected at 2keV
52W013|by the Einstein Observatory (Katgert et al., 1983ApJ...275....1K).
52W023|Blue compact emission line galaxy in group. Object just between 21 and
52W023|50cm position, but radio source is of low surface brightness. Very steep
52W023|spectrum radio source ({alpha}=1.47). Solid id.
52W036|Radio source in arm of irregular galaxy with strong emission lines.
52W042|Faint red object in component A of large unequal double source, but no
52W042|likely id between A and B. Source has no head-tail morphology, hence
52W042|the red object is unlikely to be the id. Low surface brightness emission
52W042|connects A and B, so they belong to one (unidentified) source.
53W003|Radio source in arm of interacting pair of spirals. Solid id.
53W027|Faint galaxy close to the head of a triple, V-shaped radio source.
53W034|Faint galaxy in head of a head-tail source with {alpha}=1.00. Likely id.
53W039|First ranked cluster galaxy with double nucleus (this is seen on superb
53W039|N-plate only).
53W044|Galaxy with double nucleus (this is seen on superb N-plate only).
53W051|Red, possibly stellar, object on radio axis of a resolved, possibly
53W051|unequal double source, closer to strongest component. Possible id.
53W052|Faint very red emission line galaxy (in group) at the center of low
53W052|surface brightness radio source. Very likely id.
53W058|In arm of bright spiral galaxy with double nucleus (or two knots). Closer
53W058|to the NE knot. Solid id.
53W077|Faint very red galaxy on the radio axis of an unequal radio source,
53W077|around the mid-poinnt. Likely id.
53W080|Bright blue quasar with strong emission lines in radio source that is NS
53W080|extended. Slightly displaced along radio axis. Solid id.
53W086|Faint red galaxy, possibly double, with flat spectrum ({alpha}=0.35).
53W086|Very likely id.
54W008|Low surface brightness radio source 17"S of a very bright spiral galaxy.
54W008|Large error in radio declination of SA68 causes offset. Very likely id.
54W009|Classical double radio source (22.5"), identified with a luminous
54W009|elliptical galaxy, which is also an X-ray source (Katgert et al.,
54W009|1983ApJ...275....1K). There is no obvious surrounding cluster, but the
54W009|object is at the edge of the 4m plate. the PSS shows a loose group.
54W013|Peculiar compact emission-line galaxy (very high surface brightness) with
54W013|a possible optical jet (or a superimposed object).
54W018|In arm of barred spiral galaxy. Solid id.
54W034|Peculair disturbed spiral galaxy 8"N of radii source. Larger error in
54W034|radio declination could cause offset. Very likely id.
54W049|Faint blue object close to center of tow surface brightness source.
54W049|Possible id.
54W053|Double galaxy with emission lines 6"N of low surface brightness radio
54W053|source. Offset caused by larger error in radio declination.
54W053|Very likely id.
54W068|Double source with faint blue galaxy (in group) at midpoint. Another
54W068|faint blue galaxy (also in group) is at position of B, while A is
54W068|possibly identified with a third galaxy. Both components could be
54W068|separated radio sources, each identified with a galaxy possibly in the
54W068|same cluster. Low surface brightness radio emission connects A and B, so
54W068|they belong to one radio source, with the galaxy of table4a.dat as the
54W068|correct id.
55W009|Radio source in arm of a spiral galaxy. Upper limit for radio spectral
55W009|index {alpha}<=0.29, possibly thermal. Solid id.
55W020|Bright spiral galaxy with emission lines. Source close to a galaxy
55W020|nucleus and has steep spectrum ({alpha}=1.10)) or is variable. Solid id.
55W023|Low surface brightness, closet to brightest of three galaxies.
55W023|Possible id.
55W037|4C45.17, classical double with large angular size (114") at PA~10{deg}.
55W037|Strong emission-line elliptical galaxy lies 3"S of expected position,
55W037|displaced along radio axis. Undoubtedly the correct id. Blue object
55W037|coincides with A and may be due to non-thermal (line) emission in the
55W037|hot spot. A red object is between the 21 and 50cm position of B.
55W041|Radio source at southern edge of bright elliptical galaxy. Radio source
55W041|declination probably offset by remaining grating tiny to radio map due to
55W041|vicinity of the very strong source 55W037. Very likely id.
55W043|Bright galaxy in low surface brightness steep spectrum ({alpha}=0.93),
55W043|radio source, whose position may also be affected by the neighbouring
55W043|55W037. Likely id.
55W044|Bright galaxy (in group) in low surface brightness steep spectrum
55W044|({alpha}=0.90) source, whose position is probably also affected by
55W044|55W037. Likely id.
55W058|Faint red galaxy (in group) in extended, V-shaped source with steep
55W058|spectrum ({alpha}=0.92). Object right at 50cm position. Very likely id.
55W070|Red stellar object 8"SW of unequal double radio source but not displaced
55W070|along axis. Possible id.
55W080|Faint galaxy 6"E of source that is part of a complex. Vicinity of 55W082
55W080|(~30") presumably affected its position in RA. Id possible.
55W092|Faint galaxy displaced 5"E along axis of strong double radio source
55W092|with large angular size (53") at PA=94{deg}. Could be the id, but a high
55W092|resolution radio map is required for confirmation. For the present, the
55W092|object is not regarded as the id and is not in Table 4.
55W093|Very red galaxy 4"S of low surface brightness radio source. Possible id.
55W118|Red stellar object, possibly variable, offset from radio position.
55W118|Close to better 21cm position of Oort & Windhorst (1985A&A...145..405O).
55W118|Likely id.
55W127|Bright G-star. Star is variable at 21cm (Paper I, Windhorst et al.,
55W127|Cat. <J/A+AS/58/1> and Oort and Windhorst, 1985A&A...145..405O), possibly
55W127|also at 50cm ({alpha}=1.45!). This is the only CONFIRMED galactic
55W127|identification in the whole survey.
55W136|Faint rich blue cluster, belt no obvious identification.
55W137|Complex optical image, possibly two merging spirals.
55W152|Faint red object is closer to radio position. A bright spiral galaxy is
55W152|probably the id, because it is closer to the 50cm position.
55W158|Faint galaxy, 5"NE of G-star (17m). Although the radio source is variable
55W158|(Oort & Windhorst, 1985A&A...145..405O), the galaxy is probably the
55W158|correct id, since it is closer to the VLA position (Windhorst et al.,
55W158|Cat. <J/A+AS/58/1>).
55W161|Triple sources with faint red galaxy at component B. In deeper maps
55W161|(Windhorst et al., Cat. <J/A+AS/58/1>) a jet extends from B towards East,
55W161|so B is the central component and the proposed id is probably correct.
55W161|The stellar object 12"N of A is presumably unrelated.
55W163|Stellar object, but red. Variable at 21cm (Oor and Windhorst,
55W163|1985A&A...145..405O) so it could be a star similar to 55W127.
55W165|Double source with faint red (possibly stellar) object between A and B
55W165|close to the midpoint. Another faint object is at the position of A, so
55W165|both components could be unrelated, only A being identified. But low
55W165|surface brightness radio emission exists between A and B, so both belong
55W165|to one source, for which the object at the midpoint is given in
55W165|table4a.dat
55W183|Coincides with bright knot on arm of one-armed spiral. Possible supernova
55W183|remnant or star formation region. Upper limit for spectral index is
55W183|{alpha}<0.27, possibly thermal. Solid id.
55W187|Large classical double (37") with real galaxy clone to midpoint.
55W209|Presumably a head-tail source with as id a double galaxy in the head.
55W209|Peculiar radio morphology, possibly a curved jet.
55W222|Very red galaxy closer to brightest component of a low surface brightness
55W222|double radio source. Possible id.
