CONSKY: A Sky CCD Integration Simulation
Robert J. Nemiroff &
J. Bruce Rafert
Michigan Technological University
Abstract:
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.
