As of 16:34 Mar 18 there is an updated EC
ADC calibration bank (ECCA.bfp) in $CLAS_PARMS
that contains (very preliminary) adc calibration
constants derived from analysis of MIP tracks in
the EC.
Single pixel cuts were applied to the zero B low threshold
runs 706,707,708 and histograms with MIP peaks were obtained
for each PMT/stack. The means of these histograms were
then corrected for light attenuation using the test lab
cosmic ray data.
For PMTs which saw no pixels the default gain
0.0001 Gev/ch was used.
Users should try new e- and pi0 reconstruction runs
with these constants and let me know of the results.
The old ECCA.bfp with constant gains is ECCA_old.bfp.
