This page discusses the various keywords that can be set in a plan file. Recall that the 3 letter keywords are to specified one per line. The keyword and value should be separated by one or more spaces or a tab; values for any keyword but CHIPS or SLITS can be followed by comments, so long as the comments are separated from the value by one or more tabs/spaces.

3-letter Keyword	description	example
MAS	specifies the name of the slitmask	MASKNAME: m33
RAW	in conjunction with the environment variable $DEIMOS_DATA, it specifies the location of the rawdata files	RAWDATADIR: data/11jun03
CHI	specifies which chips (1-8) to run on	CHIPS: 3,7
FLA	specifies a flat frame	FLAT: d1011_0023.fits.gz
ARC	specifies a single arc frame to be used on both the blue and red side of the detector - not intended for use with BLU and RED; when specifying multiple arc for use on a single side or both sides of the detector use BLUE and RED	ARC: d1011_0024.fits
BLU	specifies an arc frame to be used on the blue side of the detector	BLUEARC: d1011_0024.fits
RED	specifies an arc frame to be used on the red side of the detector	REDARC: d1011_0025.fits
	A single arc frame can be specified using both BLU and RED. The arc will then be used on both the red and blue sides.
POL	use polyflag method for wavelength fitting (DEFAULT)	POLYFLAG
TRA	use traceset method for wavelength fitting (NO LONGER MAINTAINED)	TRACE
LIN	specifies the arc lamplist to use	LINELIST: lamp_NIST_blue.dat
