At the beginning of the day we found that the annulus mask was not very well aligned to the incoming CO2 beam but the central mask was pretty good, so we slightly moved the annulus mask to get the beam relatively well centered but it was quite difficult because it's very sensitive, mostly due to the 7 shims sitting underneath the base.  We also re-centered on the two Irises just before the periscope and was hitting the center of the bottom periscope

Before lunch we turned on the CO2 for one minute and saw that we still had an edge of the annulus mask on the HWS.  After lunch we saw that the beam was clipping on top periscope and not very well centered at all on the viewport.  Chandra came out with us and gave the OK to remove the coupling between the table and the outer ZnSE to put the laser card closer to the injection point.  We then tried to walk the beam closer to the center of the viewport with the bottom periscope and compensate with the top periscope (only in yaw to begin with).  Unfortunately, when we tried this, the HWS didn't register another CO2 injection, so we attempted to walk back the same way to get our orientation again, and we've gotten some fringe heating back again so we still have some work left to get the pointing correct to the test mass and will go back out to the table tomorrow morning.
