[Aavso-photometry] FITS Keyword List

[Michael Newberry]

OK, I was trying to keep it simple and reduce the geekiness of my answer. If 
you want to change "well worn set of IRAF compatible keywords" to "NOAO 
dictionary keywords" then I am fine with that. All I am trying to say is 
that the keyword names have evolved over time and those that remain and are 
supported by IRAF (the NOAO set) is what we try to follow.
