Ser. 97 77 1995 1995ApJS...97...77D galaxies: clusters: individual (Coma) galaxies: fundamental parameters galaxies: photometry A homogeneous photometry catalog is presented for 450 galaxies with B25.5 <= 16 mag located in the 9.8 x 9.8 deg region centred on the Coma Cluster. The catalog is based on photographic photometry using an automated surface photometry software for data reduction applied to B-band Schmidt plates. The catalog provides accurate positions, isophotal and total magnitudes, major and minor axes, and a few other photometric parameters including rudimentary morphology (early or late type).

Num Internal number [DFO95] --- CGCG Identification from CGCG <VII/4A> --- NGC_IC Identification from NGC/IC catalogs --- UGC Identification from UGC <VII/26D> --- cz Redshift from CfA redshift survey --- RAh Right ascension (1950.0) Accuracy of equatorial coordinates are 0.6 arcsec (rms). h RAm R.A. min RAs R.A. s DE- Declination sign, always blank --- DEd Declination (1950.0) deg DEm Dec. arcmin DEs Dec. arcsec Blend Deblending flag 'A' and 'M' denote that these galaxies are deblended either automatically or manually. Manual deblending was done, when topology of the overlapping objects does not allow a unique solution, or when blended images are so large or complex that the deblending procedure requires too much computer memory. Photometric parameters may not be accurate for galaxies with these flags. --- B25.5 Isophotal magnitude B25.5. The mean error is estimated to be 0.1 mag. mag Bt Total magnitude Bt The total magnitude is obtained by fitting the growth curve at the three faintest isophotal levels (dividing the intensity range between the peak and the threshold, 25.5 mag/s, into 20 levels) to the fiducial growth curves expected for the de Vaucouleurs profile (for E-type galaxies) and the exponential profile (for L-type galaxies), and then by reading the magnitude at 5 times the effective radius. For U-type galaxies, we average the two values obtained from the two profiles. Note that the definition of this total magnitude differs from that of BT (defined by RC2) commonly used in the literature; the offset between the two total magnitudes is found to be ~0.03 mag (Bt is brighter). When a good fit is not obtained for the three points, Bt is not listed. mag a Semimajor axis at 25.5 mag/arcsec2 Semimajor and semiminor axes at a surface brightness level of 25.5 mag/arcsec^2. 7-10% errors are expected for both parameters. arcsec b Semiminor axis at 25.5 mag/arcsec2 arcsec PA Position angle of major axis deg SB25.5 Mean surface brightness Mean surface brightness defined by equation (3) in the printed paper with muL = 25.5 mag/arcsec^2. mag cIndex Concentration index defined by Eq.2 in paper --- re25.5 Effective radius Effective radius that contains half the flux of B25.5. arcsec Type E=early, L=late, U=unclassified Morphology: 'E' (early, E-S0) or 'L' (late, Sa-Im), according to the criterion discussed in section 2 of the printed paper. The confidence level of the coincidence with RC3 morphology (early or late) is 87.5%. 'U' denotes a galaxy which is unclassified. --- Star Objects found to be blended stars The objects are marked by asterisks when they are classified as galaxies by the automated software, but turned out to be blended stars ("double" stars) upon visual inspection. --- CDS 1995Jul12AAS CD-ROM series, Volume 4, 1995 Lee Brotzman [ADS] 08-May-95 UNKNOWN UNKNOWN at CDS: The blank internal numbers in table1 (col.
