MC1 damped TFs

Mark B. and Cheryl V.

Cheryl adjusted the damping gains on MC1, MC2 and MC3 to fix the overdamping observed in recent TFs. A fresh round of MC1 damped TFs will commence shortly to confirm the effectiveness. The Measurement Status indicator will go on for the duration of the measurement and then go off automatically.

New damped TFs look rather more reasonable. However even better filters and gains based on LLO experience are being installed and there'll be another round of TFs in a few days.
