    Tentative initial BCM calibration analysis data
    MCC log file 160,
    9 current steps 100, 50, 20, 10, 5, 2, 1, 0.5, 0.2 micro A
    Coda Data file 7353 seems to have first four current settings,
    and Coda Data file 7354 seems to have last five current settings

    First column, Slope of d1cnts vs clkcount
    clkcount is the 1024 kHz clock that is double pulsing at 2044 Hz
    Second column, OLO2 current from MCC file 160
    (halog 335002) http://www.jlab.org/~adaq/halog/html/1010_archive/101015110155.html
    Average OLO2 current +/- stdev/sqrt(# points in MCC file)
    (approx 100 data points per current setting)
