HISTORY imsplice: FLIPS ver 2.0 - Elixir by CFHT - Mon Mar 24 2003 - 20:40:29
HISTORY imsplice: Splicing the two readouts (A&B) per CCD into a unique image
HISTORY imsplice: Splicing results in all detectors as if read from A amplifier
HISTORY imsplice: NEXTEND keyword updated (/2) = number of CCDs vs. amplifiers
HISTORY imsplice: EXTNAME keyword becomes `ccdxx` instead of `ampxx`
HISTORY imsplice: AMPNAME keyword now covers both amplifiers (eg `29a + 29b')
HISTORY imsplice: keyword {GAIN, RDNOISE, MAXLIN} replaced by two keywords [A,B]
HISTORY imsplice: DATASEC and DETSEC keywords now reflect the entire CCD
HISTORY imsplice: BIASSEC becomes irrelevant -> replaced by BSECA & BSECB
HISTORY imsplice: New keywords are DETSECA, DETSECB, DSECA, DSECB, TSECA, TSECB
HISTORY imsplice: New keywords are ASECA, ASECB, CSECA, CSECB
