fdelhdu -- Delete an extension from a FITS file
fdelhdu infile[ext#] confirm proceed
This task deletes an extension (not the primary) of a FITS file.
Since the input FITS file is modified by this utility, an opportunity
is given to confirm before deleting the extension.
- infile [file name]
The file name and number or name of the extension to be deleted.
The extension number or name has to be specified explicitly.
- (confirm = yes) [boolean]
If set to YES, the following information (keyword values) about the
selected extension will be printed; EXTENSION, EXTNAME, NAXIS, NAXES.
- proceed = yes [boolean]
At this point the user may proceed or quit without modifying the input
If the 'PROCEED' parameter is set to NO, then the program
exits without modifying the input file.
If 'CONFIRM' is set to NO and 'PROCEED' is set to YES, the utility simply
deletes the extension without any warnings. (suitable for a script)
1. Delete the second extension from the input file test.fits.
ft> fdelhdu test.fits+2 N Y
The user has to provide the extension number or name of input file
explicitly. Otherwise the program will give a error message and quit.
ftdelhdu. fv, the interactive FITS file editor, can also be used to delete
extensions from a FITS file.
