| Abstract: |
After 17 years in orbit, two electronics failures, a mid–life servicing mission in 2009, and numerous updates to the reference files and codebase of its data pipeline, many aspects of the calibration plan for the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) have changed extensively. In this paper, we will discuss the challenges inherent to calibrating and maintaining multiple detectors (two CCDs and a MAMA) in a Low–Earth Orbit radiation environment for an extended period using a single calibration package. We will also show how the ACS calibration code compares to the other active HST instruments in its design and implementation in the automated HST data processing pipeline before data are stored in the data archive. |
