Fall '18 had two bcm calibrations and gains were stable, thus I am able to assign a 0.5% uncertainty on BCM1 charge. Spring '19 had only one bcm calibration near the end of the run cycle and calibrations had drifted over the intervening 4+ months, so I'm conservatively assigning a 1% uncertainty to Spring '19 normalization with BCM1.(The uncertainty in the pi-/pi+ ratio will be smaller.) Continued feedback from CSV and J/Psi etc is welcome.
