Remote RefCav alignment

The RefCav transmission is quite low, so Jason had put in a work permit to do a remote alignment tweak.  I'm reminding myself from alog 72222 what the procedure is (i.e. ISS stays on for this).

Attached is a several day trend of the RefCav transmission along with a temperature sensor inside the PSL enclosure.  It looks like the temperature changed, but only by 0.3 F, and that perhaps started the drift down in transmission.

Notes to future self:
