- Form: HEDIT buf
-
- buf
- is the number of the buffer holding the
image that is having its FITS header edited.
VISTA writes the FITS header associated with buffer 'buf' into a temporary
disk file and then invokes the default editor to edit the file. When you
exit the editor the modified version of the FITS header replaces the old
version.
The default editor is vi, although you can specify any other editor by
setting the environment variable VISUAL before running VISTA to be the name
of the editor you wish to use (e.g. to use emacs, setenv VISUAL
/path/to/emacs, where ``/path/to/'' is the full path to the emacs
executable on your system).
