Today we reran the mod-depth up down tests.  We are not fully trusting these numbers because we suspect we are clipping a bit on IM4_TRANS, which might artificially raise all of our estimated PRGs, including those for RF9 and RF45.
Additionally, there was obvious thermalization still happening during the measurement.  Still, the first pass measurement is useful for up to 10% estimates?
We should rerun after we recenter on IM4.

PRGs
9 MHz PRG = 85.6
45 MHz PRG = 36.6
Carrier PRG = 50.4

REFL ratios
9 MHz reflection ratio = 0.309
45 MHz reflection ratio = 0.268
Carrier reflection ratio = 0.055

EDIT:
We forgot where the POP beam diverter was, so I'm also posting some MEDMs and Guardian code snippets of where and how to reopen that beam diverter.  We have left the POP beam diverter open for now.
