edhead is a utility for editing IRAF and FITS image headers. It uses
any Unix text editor (set from the EDIOR environment variable) to edit a
FITS version of the image header.
Command Line Arguments
filename
Name of IRAF image header file or FITS file. This must be present.
-eeditor
Use this editor instead of the one specified by the EDITOR environment
variable or the default, vi.
(New in WCSTools 2.6.19)
-v
Print more information about process
-n
Write the output to a new file which is named by inserting an e
before the file extension. For example, test.fits becomes
teste.fits.. The new file is always written to the current
working directory.
Examples
1. Edit a IRAF image header and write a new image header file.
edhead -n test.imh
produces file teste.imh, pointing to the same pixel file.
2. Edit a FITS image header and write it back to the same file.
edhead test.fit
produces file test.fit, entirely rewritten so that there are
no problems if the length of the header changes.
