To summarize the work completed on the input optics installation this week: We placed the best 2 inch optics we have in the beam line leading to the mode cleaner. Using irises placed with cookie cutters we aligned the input beam into the IMC to MC2 and back from MC2 to MC3.  We then used MC1 and MC3 to get the cavity flashing (see video below) and subsequently checked the centering on the mirrors by eye.  Afterwards we used pushers and pitch adjusters (thank you Travis) to bring the electronic offsets to within 10% of their electronic range.  The HAM Auxs had their first contact removed, OSEMs centered, and damping engaged.  As of now the beam is aligned through the Faraday to IM3.  In addition, we have assembled the rigid optic mounts and many of the baffles.
