Here is the output of my own program. The fact that it matches the NA data exactly does not mean much, because I have not brought it up to date since spring 2013. The NAO may well have used a different ephemeris, precession-nutation model, delta-t and what else there might be for 2016. I did not check.
In my program you can see the "correct" GHA, the tabulation for the full hour, the GHA as if it were computed from tabulated values and interpolation tables, and the difference between the "correct" value and the one obtained through the NA.
I never even thought of offering my program to the public because I have no intention to maintain it.The code is trivial and does exactly what I described in my previous message, no more, no less.
