17.6
The STIS Cycle 9 calibration plan was modeled closely on the Cycle 8 calibration plan. Supported modes were monitored for items such as sensitivity changes, flat-field evolution, and dispersion solutions.
In addition to monitoring instrument health and safety and maintaining the overall calibration of STIS supported modes at the accuracies as established during Cycles 7 and 8, a few special calibration programs were added for Cycle 9, with the following goals:
1:
2:
3:
4:
5:
To model the ghosts (which are caused by multiple reflections in the CCD window) in the G750M grating mode.
The results of all the Cycle 9 calibration programs are presented in the close-out report STIS ISR 2003-02.
