The calibration curves below are the first ever produced self-consistently, i.e. using the EXACT same pipeline with the EXACT same parameters as the science data. No hacks were needed to produce these*. The recovered Volts/Jy are substantially higher than BGPSv1 and ALSO higher than the curve used about a year ago in an attempt to explain the v1 flux discrepancy.
Remember that a higher calibration curve means a LOWER recovered flux. I haven't finished the check, but odds are pretty good that applying these self-consistent cal curves will reduce the v2 data to be about 1.5.
