WIRO Longslit Sensitivity Plots

Figure 1: A plot showing photons/sec detected for the V=4.7 magnitude A1V star Gamma Scuti using the WIRO longslit with a 2.0 arcsec slit and the 1800 l/mm grating. Exposure times with this grating setting for other stars can be scaled accordingly. The total system efficiency near 6000 Angstroms is around xx%.
