[Cheryl, Jenne]

This is going to be a short summary, and we'll comment with more details after we've had a chance to eat dinner.  But, it seems like the correct IMC Refl beam is coming out of the vacuum onto the table, based on power meter measurements.  With MC3 misaligned, we measured about 65mW on IOT2, compared with 65-71mW on the PSL table (hard to get a good measurement at either location, but the numbers match pretty well, so it's not like this is a ghost beam or something).

In the end, we put the IMC mirrors and the PZT back to the locations that were known to be good on Wednesday (HWP was still in, but refl beam on IOT2 looked reasonable at that time).  Cheryl did some adjustments to the bottom periscope mirror in the PSL enclosure, and we seem to be getting the right beam out.  However, the beam on the table looks not so great, so we're not 100% sure that we're really happy with the refl beam, but it's at least the right beam coming out.
