Ser. 109 45 1997 1997ApJS..109...45M Galaxies, photometry Redshifts astrometry cosmology: observations galaxies: distances and redshifts galaxies: photometry surveys Redshifts, four-band photometry (U B_J_ R_F_ I_N_), and astrometry are presented for faint galaxies in four widely separated fields. We provide the necessary information to enable well-defined, statistically complete subsamples of faint galaxies to be constructed from the master catalog. The redshift survey is 86% and 71% complete to R_F_<=18.5 and R_F<=19, respectively, yielding 328 galaxies with reliable redshifts to R_F_<=19, with a median redshift of 0.142. Adding the galaxies from the fainter statistical sample yields a total of 583 reliable redshifts with a median redshift of 0.202. An additional 156 redshifts in the same fields, but not part of the samples defined here, are also given. Of the 739 galaxy redshifts presented, 212 are for galaxies with R_F_>20.

If the first run is parenthesized, then it was not observed during that run, although it was created for that run. --- Texp Total exposure time s Target List of special targets --- MKK97 Identifying serial number number=1 Objects in fields SA57, SA68, Her1, and Lynx2 begin with the digit 1, 2, 3, and 4, respectively. --- RAh Right ascension (1950) h RAm Right ascension (1950) min RAs Right ascension (1950) s DE- Declination sign --- DEd Declination (1950) deg DEm Declination (1950) arcmin DEs Declination (1950) arcsec RFmag Total R_F_ (R_F_ approx. (V+R)/2) magnitude number=2 In SA57 and SA68, this means the magnitude within a circular aperture of radius 2*r1. In Her1 and Lynx2, this means the FOCAS total magnitude (magnitude within an area at least twice the size of that contained within the detection isophote). mag U-BJ U-B_Johnson_ color number=3 In SA57 and SA68, the colors are derived from magnitudes measured in a circular aperture of radius 2*r1. In Her1 and Lynx2, the colors are derived from magnitudes measured in a circular aperture of radius 2 arcsec. The 5 off-scale values (MKK97= 103357, 103341, 213807, 217739, 316656) reflect the fact that the photometry for individual objects can be wrong due to plate defects or whatever. They clearly indicate that the photometry in at least one band for that object is questionable. mag BJ-RF B_Johnson_-R_F_ color mag RF-IN R_F_-I_N_ color (I_N_ approx.
