The BBB channel was continually going into the alarm range. It's been removed from Picket Fence FOM and EPICS.
The steps for removal were:
1. Edited /opt/rtcds/userapps/release/isi/h1/scripts/Picket-Fence/LHO-picket-fence.py. Commented out the block at line 39 that adds the "BBB" channel.
2. VNC to nuc5. Close the Picket Fecne window.
3. ssh as controls to nuc5. Run "start/launch.sh". This restarts the Picket Fence FOM, which also sets the EPICS variables.
Thanks Erik.
FYI - There are a bunch of stations around the Vancouver area, but BBB is the only one hosted by PNSN. We've reached out to see if we can get access to a similar low-latency server so that we can hopefully find a quieter station to use. These stations are useful for monitoring incoming motion from Alaska.
