You appear to be histogramming in phi, but you should get a flat distribution histogramming cos(phi). Are you later correcting for this when you check for isotropy?

Your distribution should look like sin(phi) if you are collecting it in uniform width phi bins, because of the d(cos(phi)) which comes into the solid angle.
