angle fitting program

[belmakier]

Angle fitting using same geometry backend as the sort code.

useage: mb_angle_fit

where centroids_file contains the un-doppler corrected centroids for cores gated on each segment for some reference transition. The format for centroids_file is

cluster crystal segment energy uncertainty

beta (v/c), as well as the theta, phi, alpha, and R values for each detector present are varied. The reference energy is set at 440.2 keV, this can be varied but will need to be recompiled.

An example centroids_file is included in data/ directory.
