Here are some plots comparing a power up from the end of O1, where we didn't have a significant drop in power recycling gain going from 2 Watts to 23 Watts, to one from last night.  

The first plot shows several monitors of recycling gain for the 2 power ups, plotted against time in the middle coumn and input power in the third column.  All three monitors of carrier recycling tell the same story: In december the recycling gain didn't drop significantly between 2 watts and 25 Watts, now it drops 6-8% by 23 Watts and 15-16% by 40Watts of input power. The beahvoir of AS90 drops by about 8% going from 2 Watts to 23 Watts, and 15% by 40 Watts, which is not sigificantly different from the behavoir in Decemeber.  The power at POP18 drops by 48% durring the power up, we can't compare this to December since the diode was saturated then.

The second plot shows the power on the baffle PDs durring the 2 power ups.  It shows that even before we had a bad recycling gain drop, we had a lot of power hitting the baffle PDs.
