I've added the following channels to the framebuilder: $(IFO):SUS-$(OPTIC)_L3_OPLEV_SEG1_IN1 2048 $(IFO):SUS-$(OPTIC)_L3_OPLEV_SEG2_IN1 2048 $(IFO):SUS-$(OPTIC)_L3_OPLEV_SEG3_IN1 2048 $(IFO):SUS-$(OPTIC)_L3_OPLEV_SEG4_IN1 2048 which required adding these channels to the ${userapps}/release/sus/common/models/QUAD_MASTER.mdl then recompiling, reinstalling, restarting, and restoring the QUAD test mass models: ${userapps}/release/sus/h2/models/h2susitmy.mdl ${userapps}/release/sus/h2/models/h2susetmy.mdl Before restarting, I created new safe.snap files, in /opt/rtcds/userapps/release/sus/h2/?tmy/h2sus?tmy_safe.snap in order to capture the new optical lever calibration. After restarting, I restored to the following snap files: /ligo/cds/lho/h2/burt/2012/07/27/14:00/h2sus?tmyepics.snap
