Abstract
Galaxy spectral evolutionary models are used to compute the following quantities in bandpasses available in the Space Telescope Faint Object Camera: (a) galaxy color, luminosity, two-color diagrams, and surface brightness profiles as functions of redshift: and (b) galaxy counts, and color and redshift distributions as functions of apparent magnitude. Two-color diagrams for stars of different spectral types and luminosity classes are presented to help in separating stellar from galaxy images. The behavior of the Lyman discontinuity is discussed. These predictions may be used as a guide to prepare and interpret observing runs with the Space Telescope.
