[b1_ana] Fwd: bcm asym plot

[Dustin Keller]

These changes are too big.  What I see using variation in the
calibration constant of the BCM is 0.02% for six days.  We
need something on that scale.  It looks like what this plot is
showing is the deviation in up and down.  A drift with
respect to one another, rather than the Cal. Con.
