Everything looks normal with these trends.  One note: the two downward dips in 70W amp power in WeeklyXtal.png (H1:PSL-70WAMP_PWR) are due to incursions into the PSL enclosure; this is indicated by corresponding changes in enclosure temperature, relative humidity, and laser room-to-anteroom differential pressure, found on WeeklyEnv.png.  The first is during last Tuesday (1-15-19), when Cheryl and Robert were working on the IO system (optic swap and mount damping); the second was last Thursday (1-17-19), when Peter was performing FSS measurements.
