 eg_tot

 sum energy of gamma-rays in MeV

 eg_1

 energy of highest-energy gamma-ray in MeV

 eg_2

 energy of second highest-energy gamma-ray in MeV

 M_gam

 number of gamma-rays with E > 20 keV

 E_rec

 reconstructed energy of the electron in MeV using the initial/final angles of the trajectory with respect to the beam axis

 dir_rec_x,y,z
