Retrieve header key with gethead

A quick note on gethead of WCSTools – as I have needed many times (but obviously not that many to remember it!).

Rather straightforward use: gethead HEADER_KEY image.fits
(as simple as possibly!)
If HEADER_KEY contains empty spaces then use double quotes, e.g. “HIERARCH TEL AIRM END”.

Reminder: you have to have installed already the WCSTools! (See the “Installing WCSTools” for this.)
