Correction for time dependent HV effect in barrel presampler scale in 2012.
Perform correction of E0_RAW (EMPBS) as function of run number, eta, phi to recover effective scale at 1600V at the beginning of 2012 Data are divided intwo 6 time snapshots
runs 200804-204910 (nominal 1600V for most EMBPS, 2000V EMECPS) runs 204932-205071 (20 EMBPS lines lowered to 1400V) runs 205112-211620 (22 EMBPS lines lowered from 1400 to 1200V) runs 211670-212272 (all EMBPS lowered to 1200V) (+changed in OFC / Mphys/Mcal) [main change for EMPBS] runs 212619-212742 (14 EMBPS lines lowered to 800V, all EMECPS lowered to 1600V) [main change for EMECPS] runs 212809-216432 ( 6 EMBPS lines lowered to 800V, 7 EMECPS lines lowered to 1200V)
The 1200->1600 and 800->1600 HV scale factors for the >211670 runs are derived from data For run<211670 an extra small correction is applied on top to account for the change in OFC / MphysMcal computation at run 211670 (using drift time for HV=1200V instead of old drift time for HV=2000V)
