BSC2 (Beamsplitter) tfs are clear

After BSC1 closeout on Friday, undamped transfer functions were ran over the week end on the beamsplitter for both top and middle stage. During the measurement the ISI was damped. Measurements are clean, as seen on the results attached. For some reason a factor of two-ish appeared in the M2 level tf (model=2ish*meas) in all dofs.

Attached results are presented as below :
 
1. H1 M1-M1 undamped tfs compared with the model
2. H1 M2-M2 undamped tfs compared with the model
3. H1 M1-M1 undamped tfs compared with previous H1 BS measurement (last month, after wire baffle install), and L1 in vacuum
4. H1 M2-M2 undamped tfs compared with previous H1 BS measurement (last september, under vacuum), and L1 in vacuum
