DICTIONARY VISTA_EXTENSION "VISTA" "VISTA extension-header keywords"
REVISION		"$Revision: 0.5 $"
CONTEXT			"FITS"


XTENSION	%s	Extension first keyword (h).
			Standard FITS first keyword in an extension header.
NAXIS		%d	number of axes of data array [cardinal] (h).
			VISTA data stored in multi-extension FITS, hence
			NAXIS=0 in primary header, NAXIS=2 in extension
			headers.
NAXIS1		%d	Size of first axis [pixels] (h).
			Standard FITS size of first axis
NAXIS2		%d	Size of second axis [pixels] (h).
			Standard FITS size of second axis
BITPIX		%d	number of bits per pixel value (h).
			Number of bits used to store pixel values
			Standard values are defined in NOST-100.0
			The value for VISTA IR will be
			32 32-bit twos-complement binary integer
			Value used to specify the undefined pixel values.
EXTNAME		%s	FITS extension name (h).
			Used to distinguish different extensions of the same
			type in the FITS file.
INHERIT		%c	Extension inherits primary header [truth] (h).
			Inheritance massively cuts down on extension-header size
			by removing unecessary multiplication of header records.
DET_LIVE	%c	This detector is alive [boolean] (h).
			A broken detector outputs its data anyway, this keyword
			flags the fact it is useless.
			Should migrate to IRACE dictionary.
