17.21 Cycle 27 Calibration Plan

The Cycle 27 calibration plan continues the standard monitoring programs established in previous Cycles, with minor adjustments to improve characterization of the instrument and to meet Cycle 27 GO calibration requirements. A special program was added to enable more reliable cross correlation with COS by obtaining high signal-to-noise spectral energy distributions of white dwarfs used as standards for COS. 

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