Problems with Geometry

While watching the Superbowl with a bunch of mathematicians, I realized that I am not doing the angular correlation functions correctly. I've been calculating the angular separation (γ) incorrectly. The actual formula is as follows:

cos γ = cos(90 - Dec1)cos(90 - Dec2) + sin(90 - Dec1)sin(90 - Dec2)cos(RA1 - RA2)

I need to fix this and the fact that I am not doing a periodic boundary condition around 0 -> 360.
