NAME

wcsgrid - Extract FITS WCS keywords and plot graticule

SYNOPSIS

wcsgrid [ -a<alt> ] [ -d<pgdev> ] [ -h<hdu> ] [ <fitsfile> ]

DESCRIPTION

wcsgrid extracts the WCS keywords for an image from the specified FITS file and uses pgsbox() to plot a 2-D coordinate graticule for each alternate representation found.

The FITS file may be specified according to the syntax understood by cfitsio, for example "file.fits.gz+1" refers to the first extension (the second HDU) of a gzip’d FITS file. Use "-" or omit the file name for input from stdin.

OPTIONS

-a <alt>

Plot a graticule only for the alternate representation specified (ignored if there is only one).

-d <pgdev>

PGPLOT device type (default XWINDOW, use "?" for list).

-h <hdu>

Move to HDU number (1-relative) which is expected to contain an image array. (Useful for input from stdin.)
