keyword=Correction: BCM calibrationthe previous entry (335482), did not take the double polsing clk into account. the new numbrs are:
Tentative initial BCM calibration analysis data
MCC log file 160,
9 current steps 94, 50, 20, 10, 5, 2, 1, 0.5, 0.2 micro A
Coda Data files 7353, 7354.
These number are the slope of cnts vs clkcount
clkcount is the 1024 kHz clock that is double pulsing at 2044 Hz.
Columns are u1, u3, u10, respectively
