While Ibrahim was doing initial alignment during maintence today, I moved SR3 (using sliders) and SR2 using the osem, to the positions in the second column of 77719 (-P move of SR3, May 7 10:39 pacific). 

Alena has been working with the zeemax model of what happened when our OFI was damaged, and she believes that this location is more centered in the OFI, and this data may be useful to her modeling.  We haven't recovered the range or all of the optical gain that we thought was possible before the OFI was damaged (our OMC alignment wasn't optimized when this happened), so we are hoping that a different spot may help.

When we relocked after this the range was low (~145 Mpc), the attached screenshot shows that we have more LSC coherence now.  We should be able to adjust LSC feedforward during tomorow's commissioning time to address that.
