After finishing initial alignment this morning, Mitch and I wrapped up the upgrade of the ISI to A+ spec. The last parts to go on were the vertical stops for the new .25mm vertical CPS and the vertical St0 L4Cs. All the sensors look live now, I will take some more detailed data later. Last pieces to be installed will be some spring tuned mass dampers that have been waiting for me to measure in the staging building for a couple weeks now. 

Tomorrow, I'll help with the cable routing up the ISI, and ISC can start re-installing the optics.
