I installed the ECD blocks on the R0 Top Mass/Tablecloth.  Attached is a plot showing the TF taken just before the addition, as a reference, and with the ECDs set to within a mm of touching the mass.  The green and black peaks are with the ECDs, and show significant attenuation of peaks.  We need to determine if the placement of the blocks is acceptable, or if they need some in or out adjustment. - Plot to be uploaded when test stand power is recovered.
