We need to check spot centering on PRM with camera tomorrow.
Suresh checked that we're not clipped by IP ANG/POS pickoff mirrors, but we haven't done any alignment of IP ANG/POS.
I think we should NOT do any adjustment of IP ANG/POS now. We should in fact try to recover them when doing the PRM spot centering
Tomorrow: Open ITMX door. Check with Watek that we're hitting center of PRM. Then look to see if we're hitting center of PR2. Then, continue through the chain of optics.
The motivation for removing the ITMX door was so that the scatter measurement team could check alignment of the new viewing mirror next to ETMX. After discussion today we decided that everything can be done at the X end. They can inject a probe beam into the ETMX chamber, bounce it off of ITMX and align the viewing mirror with the reflection. So we'll leave ITMX door on for now.
We should, however, inspect the situation ITMY and make sure we have good clearance in the Y arm part of the Michaelson. Koji previously expressed suspicion that we might have clipping on the southern edge of the POY steering mirror, so we need to check that out.
Koji and I discussed the situation for getting camera face views of BS and PRM. Koji said the original idea was to see if we could install something at the south-east view port of ITMX chamber. Steve also suggested utilizing the "ceiling" camera mounted on the top of the IOO chamber.
End X tasks:
