GENERATING COLORS AND K-CORRECTIONS FROM EXISTING CATALOG DATA

We present color-color relations on several systems as functions of redshift calculated using the galaxy energy distributions of Coleman et al. [ApJS, 43, 393 (1980)] which span the run of Hubble types. The system response curves of five different photometric systems {Johnson UBV, B(J)RI [Gullixson et al., ApJS (in press) (1993)],.Thuan-Gunn gri, Sloan Digital Sky Survey u'g'i'r'z', and Cousins R(c)I(c)} and the absolute spectral energy distributions of spectrophotometric standard stars were used to tie the different systems together. We have calculated zero points on the AB79 system for all of these bands, m-B colors for each band and each galaxy type as functions of redshift, and B k corrections for each galaxy type, To the extent that galaxies represent a one-parameter sequence in color space, a redshift and color in any pair of bands in any system can be used to estimate the colors in any other using the tables and graphs constructed here.
