This afternoon, Rod and Travis checked out the ESD cables, as post fixing and baking test had not been done yet. Preliminary results indicate the cable is fine. Then Travis and I worked to align the outstanding Top Main chain BOSEMs, and lower stage OSEMs. All L0 (Tops) and L2 (PUM) are done. We ran into issues with L1 (UIM) LR in that the signal is completely flat and the BOSEM is unresponsive to any shadow. We will disconnect the cable to the problematic LR BOSEM and attach a new BOSEM to the cabling to identify where the problem is... Garcia is going to make a round of TFs (last nights were problematic) tonight via the Top BOSEMs.
