Pre-Glass Installation Measurements of H1-SR3
Jeff B & Andres R

   We moved the HLTS suspension SR3 into position to have the metal Bottom Mass replaced with the Glass Optic. We took height and blade tip breakoff measurements as a pre-installation base line. All measurements are within tolerances. 

Measurement Point            Target/Tolerance  	                         Measurement 
Top Blade Wire Breakoff       806.12mm	                                 804.93mm, 805.89mm 
Bottom of T-Block                 552.23mm	                                 552.60mm
Top of Intermediate Mass     461.63mm	                                 461.63mm
Lower Blade Wire Breakoff   608.84mm tip coplanar <0.5mm  607.75mm, 608.11mm, Coplanar = 0.36mm
Top of Bottom Mass              291.0mm +-1mm	                         291.17mm

   The next step is to center and adjust the OSEMs, and then run Phase 2A Transfer Functions.

The OSEMs have been re-centered and then retracted for taking the OLVs. A D1000234 quadruple cable needs to be attached before running the "PrettyOSEMgains" script.
