FITSEDIT - Edits the FITS extension of an NDF

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.
