ECR E1400078 M1V&R to M2P&Y Damping Path installed on H1SUSBS
J. Kissel

As per ECR E1400078, I've installed the infrastructure for damping the highest vertical and roll modes of H1 SUS BS (a BSFM triple suspension), sensed at the top (M1) stage, and actuated upon using the middle (M2) stage pitch and yaw drive. Many thanks to Stuart for prototyping; install was as simple as an update to the userapps repository, and then a recompile, reinstall, restart, and restore. A new safe.snap has been captured and committed with the input to the new filter banks turned off. The DAQ was restarted later in the afternoon to account for new channels (and other bugs from the network outage).

This closes out ECR E1400078, and completes integration issue 723.

Once we get back under vacuum, we'll begin to commission the loops in a similar fashion as LLO -- hoping that we have a similar amount of SNR and control authority.
