Ralph C. Bohlin,George F. Hartig,Andre Martel +2 more
- 01 Dec 2001
TL;DR: In this paper, the authors measured 157 LP-flats with simulated sky illumination of the CCD cameras for supported and many unsupported ACS modes, including 13 and 17 single filter flats for WFC and HRC, respectively, 78 polarizer mode flats, and 34 flats of all types for the HRC coronographic mode.
