Driver program that calls inject_eff() periodically to calculate the momentary injection efficiency for HER or LER.
ref_magshr:inject_eff.c
This module calculates the momentary injection efficiency for HER or LER. Toroids with the special readout bit have their values recorded in any BPM ring buffer which may be created in that micro. This routine reads those in PI01 and PI11 for comparison with the BIC measured bucket increments, resulting in a pulse-by-pulse injection efficiency.
ref_magshr:save_lumi.c
save_lumi - Saves the important luminosity_f data to disk using logical name BIC_LUM_DATA
restore_lumi - Needs to synchronize with the sequencer program on the BIC ioc which updates the luminosity.
