Summary of the Post-COSTAR Side 2 Sensitivity Monitors for GHRS
Abstract
The sensitivity of the GHRS on Side1 and Side2 has been measured approximately every 3 months since Cycle4. The measurements were done with the ultraviolet flux standard BD+284211. Significant time dependence was detected in the Side1 data, and led to a recalibration of the G140L sensitivity, as discussed in GHRS-ISR-085. Trends are also detected in the Side2 sensitivity monitors, although they are much less than those found for G140L.
