Expected Performance

The expected limiting magnitudes for S/N=5 and 10 from 1 hour exposures as a function of read noise in a single pixel are presented in Figures 8 and 9. Included are the effects of sky noise, readout noise, combining the signal from the two MODS, the size of a resolution element, and system throughput. In addition to plots for resolution of 2000, 8000, and 16,000, calculations were done for slit widths of 0.6 arc-sec, 0.3 arc-sec and 0.15 arc-sec, which correspond to admitting sky light from 0.36, 0.09 and 0,0225 arc-sec2.
