reference cavity transmission
/* waffle, random thoughts & meanderings below */

Plots of the reference cavity and pre-modecleaner transmission for the past day.
slope of reference cavity transmission 0.27 mW/day
slope of pre-modecleaner transmission 110 mW/day

slope of QPDY 0.002 microns/day
slope of QPDX 0.003 microns/day

We should crunch some numbers to see if this is consistent with the beam change
out of the pre-modecleaner,  The laser output power actually fell over the same
time interval.  The diffraction average has decreased to suit.

Comparison of the cavity spots over the past week can be seen in AlignmentShift.gif.
