To help with setting up SDF files, I have created lists of channels modified by the H1 guardian nodes for the month of January up to this time. We expect this to be a fairly exhaustive list as it covers the RCG2.9 upgrade on the 13th Jan when all front ends were restarted.

There is a text file per guardian node in the directory /opt/rtcds/lho/h1/data/guardian_channels/guardian_control_channels/2015jan

Attached is a list of the number of channels controlled per guardian node. As expected it is quite small. For example: SUS_ETMX has 1,717 set point channels of which 53 were changed (3%); ISI ETMX (ST1 and ST2) have 1,952 set point channels of which 124 were changed (6%).
