Here are some plots to illustrate the alignment progress described in Jenne's alog 29457

The first attachment shows various powers plotted against input power for a power up with the old PRC alignment (blue) and the new PRC alingment (orange). 

You can see that we are still loosing recycling gain as we power up, but less so than with the old alignment.  We know that we can move the PR2/POP offsets a bit more; we stopped where we did last night because we started to rail the POP PZT and had to realign on the in air table.  You can also see that the sideband powers are not dropping quite as much as with the old alignment, although we start with POP 18 lower. 

The bottom row shows REFL normalized by the input power; the plot below shows normalized refl power vs recycling gain.  (Time during the power up goes from right to left on this plot).  You can see that as the alingment gets worse the interferometer is approaching critically coupled, with the old PRC alignment the reflected power starts to increase again for recycling gains below about 27.
