Description:
This procedure
allows you to use your favourite editor to modify the
FITS headers stored
in an
NDF’s FITS extension. There is limited validation of the FITS headers
after editing. A FITS extension is created if the NDF does not already have
one.
Usage:
fitsedit ndf
Parameters:
NDF = NDF (Read)
The name of
the NDF whose FITS extension is to be edited.
Examples:
fitsedit m51b
This allows editing of the FITS headers in the NDF called m51b. Notes:
-
This uses the environmental variable, EDITOR, to select the editor. If this variable is
undefined vi is assumed.
-
The script lists the headers to a temporary file; allows text editing; and then
replaces the former FITS extension with the modified version, performing some
validation at this stage.
