keyword=Analysis: Cavity bcm calibration using run 11644

The calibration constants posted here are effective for the run range

11541-11560

and the constants are:

                 pedestal       gain
qwk_bcm5        ,5715.04,       0.00146555
qwk_bcm6        ,7042.88,       0.00160408

The plots showing these constants and the cross-check for the goodness of the calibration are shown in figures 1 and 2.

This calibration was done due to the event that turned off bcm5,6 electronics in the counting house on April 21 day shift as posted in hclog entry https://hallcweb.jlab.org/hclog/1104_archive/110421223801.html. The above run range had wrong gain settings for bcm5,6 in the bcm5,6 montecello.
