I resumed line tracking on the front-end model with tentative (not finished cross-check) results in klog#34033.
Some EPICS parameters for the line tracking are also accepted in klog#34035.
They will be update again with finalized parameters after the cross-check (it shouldn't make so large changes).
Though degeneration between the cavity pole and optical gain is so large, it seems to work well with poor accuracy as shown in Fig.1.
Line tracking parameters are updated with finalized reconstruction parameters in klog#34048.
Updated channels are K1:CAL-CS_TDEP_{SUS,PCAL}_LINE?_REF_* which are available on MEDM screen for reference model records (see Fig.1).
After then, corrections in pcal beam position in klog#34039 were also taken into account for line tracking parameters. Pcal correction had been done by two component one was in filterbank module for compensating XPcal and Ypcal, and another one was residual functions of Pcal in order to switch used pcal easily. But residual function also depends on Xpcal or Ypcal now. So there was no longer working to make management easy. So I merged a correction factor in the filterbank module to one in reference TF on the EPICS records (see Fig.2)
There is no change that we need to re-calculate reference TF at line frequencies if we switch used pcal (X or Y). On the other hand, pcal correction factor which we need to manage becomes only one (K1:CAL-CS_TDEP_PCAL_LINE?_CORRECTION_{REAL,IMAG}) for each line.
