The Arctic Monkeys

It's been a fairly productive past few days. I've got stars in Radial Distance, RA and Dec instead of X, Y, and Z (as well as galactic latitude and longitude), decomposed velocities into proper motions and radial velocities, read about the "Field of Streams" and halo formation models, and I learned (thanks to Maya) how to write out a fits file with all of the newly calculated data. At least, I think I did that last part correctly. Tonight I'll be testing that, but I'm confident that it worked.
