VIII/3      An Optical Catalogue of Radio Galaxies       (Burbidge+ 1979)

An Optical Catalogue of Radio Galaxies Burbidge G., Crowne A.H. <Astrophys. Journ. Suppl. 40, 583 (1979)> =1979ApJS...40..583B
ADC_Keywords: Galaxies, radio; Redshifts; Radio sources; Galaxy catalogs Description: This catalog contains basic optical information on all known radio galaxies (with L[radio] greater than about 10**[41] ergs/s) that had been identified as of 1979 and for which measured redshifts were available. The data include the right ascension and declination (1950); galaxy (optical) type; visual magnitude; photoelectric colors; redshift (z) and the spectral lines on which the redshift measurements were based; coordinate designations; radio flux and frequency; radio spectral index; other names; and the references for the galaxy identification, photometric data, redshift, radio flux, radio spectral index, and radio map number. Note that the ADC version of this catalog differs somewhat from the original printed catalog in that some fields were added or modified and other fields reordered. In addition to the catalog data file itself, two additional files containing the list of references for the catalog are also available. The first reference list is in alphabetical order, and the second is in numerical order. File Summary:

Note on q_RAs: Precision indicator of the right ascension; the right ascension is given as HH MM with eight possible significant digits. The precision indicator identifies how many of these eight digits are given as blank (i.e. not known) and so may vary between zero and eight. Note on q_DEs: Precision indicator of declination: the declination is given as DD MM SS.S with seven possible significant digits. The precision indicator identifies how many of these seven digits are given as blank (i.e. not known) and so may vary between zero and seven. Note on EqPos: Code for equatorial position: blank = optical position given taken primarily from papers reporting the redshift and identification papers. R = radio position given ("*" in published catalogue). Note on OptType: Optical type code - left justified in field. The type codes and their statistics are given in "Table A-2" section below. All types and cluster information (cf. bytes 38-39) is drawn from either the identification reference (cf. bytes 25-27) or the redshift reference (cf. bytes 81-83). Note on Rdesc: Radio description which is no longer used. If these bytes are not blank then given object is in a cluster. The radio description codes and their statistics are given in "Table A-3" section below. Note on Vmag: Visual magnitude. These values are very uncertain since very few photometric measurements have been made. Note on Z: Redshift. Most of the redshifts listed are uncorrected for galactic rotation. Note on n_Z: Redshift (cf. bytes 63-68) qualifier: blank - if the value of the redshift (z) is not corrected for galactic rotation. "C" - if z is corrected ("*" in published catalogue) "Q" - if unknown if z has been corrected ("?" in published catalogue). Note on LineType: Spectral lines type: "A" - if absorption lines. "E" - if emission lines. "AE"- if absorption and emission. Where no spectral-line lists have been published but mention has been made of the appearance of absorption or emission, it is noted with an "A" or "E" in these bytes. Note on Name: Coordinate designation given as HHMMSDDX based on equatorial coordinates at epoch B1950.0 where: HH = hours of right ascension MM = minutes of right ascension S = sign of the declination DDX= declination (unit=0.1deg) Note on Sp-Index: Radio spectral index between 408 and 1400 MHz. The spectral index alpha is defined by S(nu) = K. nu**(-alpha) In the published catalogue the symbol ">" following the value of the spectral index indicates a range between 408 and 5000 MHz and the symbol "<" indicates a range between 178 and 408 MHz. No attempt has been made to extrapolate where fluxes have been given at other frequencies (cf. byte 115). Note on SIcode: Code for spectral index range. This code is for the symbols ">" and "<" as defined above in bytes 102-106. The ">" is coded as an "A" and the "<" is coded as a "B". This byte is blank if other than these two spectral indices. See the file "refs". Note on SpNum: Number of spectral lines used in the computation of the value of the redshift. This number ranges from 0 to 20. Note on Lines: List of 20 coded spectral lines. The coded values range from 01 to OR and are defined in "Table A-4" section below. The N (cf. bytes 116-117) coded values are at the beginning of this field and the remaining bytes are blank. Note on Arefs: Additional references are five characters each where the first three represent the reference number (file "refs") and the two letter code for the type of reference as follows: ID - identification FC - finder chart Z - redshift S - radio flux (S) SI - radio spectral index (SI) M - radio map Note on Alias: Other names - maximum of seven names separated by commas with no embedded blanks. "Table A-1" section below gives the codes used in these fields along with their full reference to the published literature.

NOTE: Ohio sources may be found in the catalog by noting that the name is a coordinate designation. The second letter (B-Z, omitting the letter O) gives the hours of right ascension, the first digit gives the declination in 10degrees increments, and the last two digits give the right ascension to 0h01 (thus OQ 172 has 10deg < delta < 20deg and alpha = 14.72h).

C5 was defined as Abell 779 in the original documentation for this catalogue, but this code was not found for any of the records. However, since the first data card for #154 (coordinate designation 0812-029) was missing, this could account for the discrepancy. This particular galaxy was counted in.the blank code. Since this piece of datum does not appear in the published catalogue there was no way to identify what the radio description code should have been.

H. Crowne) in the summer of 1981. Extensive modifications to the format of the machine-readable catalogue have been made. Originally the magnetic tape consisted of card image records on one file which contained the data (five cards per entry) followed by the references. This single file has been divided into two separate files: a data file and a reference file. There are 495 data records and 412 reference records each on a separate file. In addition, the reference file is sorted numerically to generate the three file magnetic tape described herein. The numbers which quantitatively define the precision of the components of the equatorial coordinators have been computed and added to the records to readily identify less precise coordinate availability. Information in byte 24 of the original first data record was moved to byte 28 to add the computed precision indicator for the declination. The coordinate designation, which is the key identifier in the published catalogue, was computed from the given coordinates and added to each record (cf. bytes 73-80) since it was not originally given on the tape for the majority of the records. The number of spectral lines present and the number of additional references have been computed for each record and added (cf. bytes 116-117 and 158-159 respectively in file "refs". One object (#154, 0812-029) had the first of the five data cards missing. The data have been reconstructed from the published catalogue whenever possible. There are several data items that are given in the machine-readable version of the catalogue that are not in the published catalogue and so the values of these were not reconstructed for the missing data record. The radio description (cf. bytes 38-39, file "catalog") is given in the machine-readable version with the note that it is no longer used, but not in the published catalogue. The photometric colors (B-V) and (U-B) are given for very few of the entries in the machine-readable version but also do not appear in the published catalogue. This is also true of the photometric reference for the data values. The frequency (MHz) is another quantity that appears in the digital version of the catalogue but not in the published version. Embedded blanks have been removed from the other names field and commas have been added to separate entries. A sequential counter (range 1 to 495) was added to each data record. The record preceding the references on the original tape contained the number 411 (actually there are 412 references) and was removed. In addition, the last record was a "999" to designate the last card image record was removed. Some references were on a single card image and some continued onto a second card image. The information has been joined together into a single record of equal length for each reference. The counter in the reference file was also inconsistent where some had leading zeros and others did not, and some had the period (".") following the number and others did not. The file that has been produced is consistent in these matters and is defined in file "refs" of this document. Table A-1 is a list of the many designations used in the other names field (cf. bytes 220-269, file "catalog") and the full reference for each. This table was prepared utilizing the information in the published catalogue. Tables A-2 and A-3 respectively represent statistics compiled during the preparation of this document. The statistics are for the counts of coded optical types and radio descriptions respectively. Table A-4 is information originally supplied by the authors and provides the code for spectral lines used in the determination of the redshift (z) value. The user of this catalogue is advised to use the other identifier correspondences available in the published catalogue whose reference is given below. * June 1993: modifications at CDS (F. Ochsenbein): The printed document was used as input for the present documentation. A few misalignments in the file "catalog" have been corrected in records ("Seq") numbers 2, 20, 114, 132, 154, 202, 237, 240, 251, 263 and 428 Acknowledgements: The original ADC documentation by Theresa A. Nagy and Robert S. Hill (1981) was used to create this ReadMe file. References: Burbidge, G. and Crowne, A.
