[Console] FOCSIM Exposure Simulation Set-up

This form will calculate the count rates for a simulated direct image of ONE point source in a 512X512 FOC image with an average value for the background.
Relay: F/151 F/96 (Pre-COSTAR)

Calculate exposure time to reach a S/N of
Calculate S/N reached in an exposure time of

Use an Observed -or- a Theoretical PSF.

Choose a spectra

from the Calibration catalog of observed spectra:
or, created by FOCSIM that is either:

The spectra will be normalized to a flux of
at Angstroms.
Note: Simply specify a reference wavelength of 0 for U,B, or V magnitudes.
