Testing H1- MC3
   We have been working on resolving a post creek bake misalignment problem with the lower blade break off heights on H1-MC3. We have tuned out a lot of the difference, but the break off heights are still slightly out of spec. We are going to take transfer functions of the M1 level to see if MC3 performance is within tolerance despite the misalignment of the lower blade break off heights.  
  
   These are the open light values for BOSEMs on HSTS MC3. The offsets and gains, listed below' have been entered into MEDM. The BOSEMs have been adjusted to 50% light. Plan is to take a set of TFs tonight when the lab is quiet.
