A brief cookbook can be found in Astronomy and Astrophysics, v.431, p.L1-L4 (2005) . Just in a case someone might need it sometime :).

Hello, I have been trying to compute the velocity of the star with respect to its local medium from the proper motion measurements. Sure, you can calculate the corresponding velocities by v = 4.74*(proper motion)*distance (in suitable units), but this resulting velocity is now with respect to...

Hello, thanks for all the help guys. I've managed to get the program working. I now see what I did wrong. Your post was especially helpful, Nascent.

Yes, I'm aware of that. Writing prog --t --v 3 would result in a GetoptError, but I do not need to accommodate this mistake into the program. For now I'm concerned about prog --v 3 or prog --t 3 or only prog cases
