Subject: MC tweaked further 

I tilted the periscope beam and aligned the MC.  Now the spot at the Faraday entrance is near the center of the aperture in up/down space.  The arm powers are only going up to ~0.8, though.  Maybe we should try a little bit of left/right. 

I looked at the IP POS spot with a viewer card, and it looked round, so no obvious egregious clipping in the Faraday.  Someone might take a picture with one of the GigE camera and get us a beam profile there.

We no longer have an MC1 and MC3 camera view.

I can see a bright scatterer that can be seen from the east viewport of the BSC, but I can't tell what it is.  It could be a ghost beam. 

It would be nice to get an image looking into the north viewport of the IOO chamber.  I can't see in there because the BS oplev table is in the way.
