Betsy, Rahul

This afternoon, Betsy adjusted the SD magnet on the OFI and we confirmed that it is sitting correctly in it's place. Next, she inserted the AOSEM and centered it on the magnet (polarity was already checked). We also took this opportunity to take the OLC/offsets/gain for the SD aosem, which is given below,

OLC = 17000, offsets = -8500, Gain = 1.739 (30,000/OLC). This has accepted in the SDF.

The in-air transfer function measurement results are attached below (we took only 3 averages) and they look healthy for all three dof - template at /ligo/svncommon/SusSVN/sus/trunk/OFIS/H1/OFI/SAGM1/Data

We then started attaching the OFI shroud as per D11800103 - the top two, side (+X side) and front shroud has been attached. Mitchell joined us to help with attaching the top and one of the shrouds. There are two/three more panels left to be attached, which will be done once Sheila is done with the beam alignment check.
