Time-dependent parameter ("kappas") trends calculated from two lock stretches on September are attached to this report.

It seems that the front-end produced fairly smooth kappas several hours after the most recent update of the front-end setttings (LHO alog 29992). See figures 1 and 2.

However, from later lock stretches on September 30 (after the Tuesday activites), it looks like the synchronized oscillators for SUS line were synched with an incorrect phase of 143.6 degress w.r.t. each other (see KAPPA_TST values in Fig. 3 and TF phase in Fig. 4). A similar issue was reported in the previous report (LHO alog 29992). I was able to fix the problem for this particular line by resetting the line frequency to 0 Hz (turning off the line) in the SUS-ETMY model and then setting it back to its nominal state 35.9 Hz (see Fig. 5). We probably need to check "FIXED_PHASE_OSC_WITH_CONTROL.c" for bugs.
