HST INS Work Item Data Sheet

1. SI/Title: STIS/E-Mode Sensitivity Uncertainty Due to Monthly Offsets

2. INS Lead: L. Dressel

3. Description of Work:
This activity is related to the E-Mode Sensitivity calibration but is
listed separately because it includes the complicated effort to derive
a correction for the so-called Monthly Offsets and their associated
blaze shifts, which do not repeat well for a given month of the year
(i.e., the time dependence of the amplitude of the blaze shifts is
currently not adequately corrected for). This effort shall be performed
for both primary and secondary central wavelength settings, as they
have had similar usage by GOs. This activity will involve writing at
least one ISR, and may involve the need for code changes within
CALSTIS.
