Hello Bill,
I looked at the file messier.hee and saw that there are some data that I did not understand what they relate and where you can find.
Let me explain:

^ M 1 Nb Ga Tau 05 34 31.9 +22 00 52 / / gr 83.6329, 22.0144 53 ^ 1952 CED 53, Crab Nebula, Taurus A;

gr 83.6329, 22.0144 what these values mean?
Sincerely
Antonio De Pieri
