wcsware – Extract WCS keywords for an image
Synopsis
wcsware [-a<alt>] [-f] [-h<hdu>] [-p] [-x] [<fitsfile>]Description
wcsware extracts the WCS keywords for an image from the specified FITS file, constructs wcsprm structs for each coordinate representation found and performs a variety of operations using them. The FITS file may be specified according to the syntax understood by cfitsio, for example "file.fits.gz+1" refers to the first extension of a gzip’d FITS file. Use "-" or omit the file name for input from stdin.
Options
- -a<alt>
- Specify an alternate coordinate representation to be used (ignored if there is only one).
- -f
- Apply wcsfix() to the header.
- -h<hdu>
- Move to HDU number (1-relative) which is expected to contain an image array. (Useful for input from stdin.)
- -p
- Print the struct(s) using wcsprt() (default operation).
- -P
- Same as -p but don’t print a default struct.
- -x
- Convert pixel coordinates, obtained from stdin, to world coordinates using wcsp2s().
- -w
- Convert world coordinates, obtained from stdin, to pixel coordinates using wcss2p().
