Query: A photometric study of faint galaxies in the field of GRB000926   We present our B, V, Rc, and Ic observations of a 3.6' x 3' field centered on
the host galaxy of GRB000926 (RA(2000.0)=17h04m11s, DEC(2000.0)=+51d47'9.8'').
The observations were carried out on the 6-m Special Astrophysical Observatory
telescope using the SCORPIO instrument. The catalog of galaxies detected in
this field includes 264 objects for which the signal-to-noise ratio is larger
than 5 in each photometric band. The following limiting magnitudes in the
catalog correspond to this limitation: 26.6(B), 25.7(V), 25.8(Rc), and
24.5(Ic). The differential galaxy counts are in good agreement with previously
published CCD observations of deep fields. We estimated the photometric
redshifts for all of the cataloged objects and studied the color variations of
the galaxies with Z. For luminous spiral galaxies with M(B) < -18, we found no
evidence for any noticeable evolution of their linear sizes to Z~1.
