The value field shall contain an integer that specifies the number of bits that represent a data value in the associated data array. BITPIX = 0 for the primary header. For an image extension, 16 is uncalibrated and -32 is calibrated. For group information captured in an ASCII table extension BITPIX = 8, denoting that the array contains ASCII characters.
