ACS Calibration Plans by Cycle

The calibration plan for a given HST cycle consists of several proposals designed to execute exposures like darks, biases, and flats, that are used to generate ACS superdark, superbias, and flat-field reference files. These calibration exposures are also used to monitor detector statistics, including bias, dark current, and read noise levels, as well as track CTE in the ACS/WFC, among other uses. See below for all the calibration plans executed over the lifetime of the ACS.
