Information keywords

The next table shows the keywords which brings image information. This are the most common ones

KEY NAME	TYPE	PERMISSIONS	COMMENT
OBJECT	STR	RW	image title
OBSTYPE	STR	RW	observation type
UTSHUT	STR	R	UT shutter opens
OBSERVER	STR	RW	observer (s) names
COMMENT	STR	RW	image comment
SOFTVER	STR	R	software version
HDR_REV	STR	R	header module version
EXPTIME	FLOAT	RW	exposure time (secs)
COADDS	U16	RW	coadded images
FSAMPLE	U16	RW	fowler samples
CCDSUM	STR	R	binning in 'X Y'
NAMPSYX	STR	R	number of amps in Y X
READTIME	FLOAT	R	total readout time
BPP	U16	R	bits per pixel
GEOMETRY	MACRO	R	adds WCS keyword
TCSINFO	MACRO	R	adds TCS info keywords
FILTINFO	MACRO	R	adds filter information

GEOMETRY: add the geometry keywords. The set of keywords depends on the specific WCS module in use.
TCSINFO: format will depend on the TCS info header file
FILTINFO: contents 1 entry per filter, with this format:
wheel1name = 'fil1'
wheel2name = 'fil2'
......
wheelNname = 'fileN'

wheelname is the name given to the specific filter wheel. See the Filter list configuration file document for more information on this
