Sudarshan, Rick
We saw some transient in Pcal laser power in our recent observation. The power variation in these transients are about 20% at its max. We are working on to find where the issue is. Until then, donot trust Pcal calibartion to more than 50% (over-estimation) of what it reports.
We think we have identified the source of the problem and devised a relatively simple remedy. See aLog 17145.
