Jeff, Dan, others...

Sheila and I noticed last night that the ETMY L2 stage RMS current watchdog had tripped - the circled indicator lights in the first figure were red.  Today with Jeff we tested whether this has any effect on the L2 actuation and reset the watchdog.

Turns out that with the watchdog tripped you can still actuate on the L2 stage, but with about 3x less force at DC than with the watchdog untripped.  So, maybe this explains our crummy alignment stability last night.

The second plot shows the effect of applying a large offset in pitch to ETMY L2 before and after the watchdog was reset, as observed by the optical lever.

I've added the SUS-ETM{X,Y}_BIO_L2_MON channels as conditions to the ETM warning lights on the OPS overview screen.
