initialize_det_geometry

gdt.missions.fermi.gbm.localization.dol.legacy_functions.initialize_det_geometry(verbose=False)[source]

Contains geometry from rmk of 07/07 Given nai el & az, calculate unit vectors in SC frame of each NaI Tested 08/14/07 – produces correct unit vector angles as per geometry from rmk of 07/07.

Parameters:

verbose (bool) – Print info to screen when True

Returns:

  • nai_az (np.ndarray(12, float32)) – Azimuth position of each NaI detector on spacecraft in degrees

  • nai_zen (np.ndarray(12, float32)) – Zenith position of each NaI detector on spacecraft in degrees

  • nai_unit_vec (np.ndarray(12, float32)) – Unit vectors along the direction of each NaI detector on spacecraft

  • back_unit_vec (np.ndarray(12, float32)) – Unit vector along the anti-direction of each NaI detector on spacecraft
