(Alexa, Sheila)

We were able to get the retro-reflected beam off of ETMX back onto ISCTEX. We adjusted the PIT and YAW offset of the TMS to the following values:

YAW: -297 (originally -224)

PIT:  -3 (originally -13)

ETM offsets remain off

We have improved the mode matching between the outgoing and reto-reflected beam by moving ALS-L7 two inches toward PZT 2. By looking at the iris with a viewer, the shapes and sizes of both beams look good and matched.

We have also aligned the retro-reflected beam onto the PD.
