[gnuastro-devel] [task #14340] Defining arbitrary variable and its value in FITS headers

[Lee Kelvin]

Follow-up Comment #1, task #14340 (project gnuastro):

Hi Mohammad, 

Another option I've come across before to allow for long FITS keyword names is
use of the HIERARCH convention:

https://heasarc.gsfc.nasa.gov/docs/software/fitsio/c/f_user/node28.html
<https://heasarc.gsfc.nasa.gov/docs/software/fitsio/c/f_user/node28.html>

This is a standard developed by ESO and fully supported by CFITSIO. Many FITS
viewer applications also support it.

To quote the link above: _"Basically, this convention uses the FITS keyword
'HIERARCH' to indicate that this convention is being used, then the actual
keyword name begins in column 10 and can contain any printable ASCII text
characters, including spaces. The equals sign marks the end of the keyword
name and is followed by the usual value and comment fields just as in standard
FITS keywords."_

This could be another potential option to allow for long keyword names.

Best,
Lee Kelvin
