GENERATING COLORS AND K-CORRECTIONS FROM EXISTING CATALOG DATA

We present color-color relations on several systems as functions of re dshift calculated using the galaxy energy distributions of Coleman et al. [ApJS, 43, 393 (1980)] which span the run of Hubble types. The sys tem response curves of five different photometric systems {Johnson UBV , B(J)RI [Gullixson et al., ApJS (in press) (1993)],.Thuan-Gunn gri, S loan Digital Sky Survey u'g'i'r'z', and Cousins R(c)I(c)} and the abso lute spectral energy distributions of spectrophotometric standard star s 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 corre ctions for each galaxy type, To the extent that galaxies represent a o ne-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 othe r using the tables and graphs constructed here.
