17.18 Cycle 24 Calibration Plan

The Cycle 24 calibration plan continues the standard monitoring programs established in previous Cycles, while adjustments are being made as necessary to better characterize the instrument and to meet Cycle 24 GO calibration requirements. A special program was added to observe three HST white dwarf standard stars to verify the spectrophotometric stability of the stars observed for the MAMA and CCD spectroscopic sensitivity monitors. Simultaneous parallel observations with the STIS/CCD, WFC3/UVIS, and ACS/WFC detectors were included to monitor the focus offsets between the three HST instruments.

A detailed summary of the calibration plans can be found on the STIS Calibration web page.
