Comment to ETMY IP healthy check (8203)

After the Cryo people released the paylod, I checked the IP status again.
I measured the TFs  in the following configuration: L = -187 microns, T = 135 microns Y = -35 microrad.
I attach  here the results (Pic 1 Pic2 and Pic3).
According to these measurements, it seems that now all the pendulum masses are free to move:
1) all the resonances of TFs L and T, have a high quality factor;
2) First peak (in both TFs L and T) is at around  70 mHz;
3) The  TF for Y does't changed.
I tuned the Damp filters for L and T and I turned on the loops.
