This program addresses the question of what resources are needed to
produce a continuous data record of the entire sky down to a given
limiting visual magnitude. Toward this end,
the program simulates a small camera/telescope or group of small
camera/telescopes collecting light from a large portion of the sky.
From a given stellar density derived from a Bahcall -
Soneira Galaxy model, the program first converts star densities at
visual magnitudes between 5 and 20 to number of sky pixels needed to
monitor each star simultaneously. From pixels, the
program converts input CCD parameters to needed telescope
attributes, needed data storage space, and the length of time needed to
accumulate data of photometric quality for stars of each
limiting visual magnitude over the whole sky. The program steps
though photometric integrations one second at a time and includes the
contribution from a bright background, read noise, dark
current, and atmospheric absorption.
