Joe and Bria have discovered a small bug in the future monitoring of the IFO response parameter time-dependence regarding the use of the sub-function atan2 (see LLO aLOG 27214). As such I've svn up'd the affected library part, 
/opt/rtcds/userapps/release/cal/common/models/CAL_LINE_MONITOR_MASTER.mdl
and recompiled, restarted, and restored the model to the OBSERVE SDF file (which I'd reconciled before restarting).
