COMMENT
COMMENT   This extension provides, for Detector #2 of the FPMA, the list of
COMMENT   user-defined bad pixels.
COMMENT   The BADFLAG column contains the bad pixel flags. These are a
COMMENT   combination of the following bit settings:
COMMENT
COMMENT   b0000000000000001 Bad pixel from on-ground CALDB Bad Pixel File
COMMENT   b0000000000000010 Disabled pixel from on-board software
COMMENT   b0000000000000100 Bad pixels in the file provided by the user
