I rediscovered some old, unused channels in the CAL-CS model for calculating time varying parameters that are deprecated (see attached screenshot). As a reminder, we have updated the way time varying parameters are calculated (see T1500377 and, more recently, T1700106). During O2, we implemented SRC detuning tracking using a low frequency Pcal line, and at that point, the CAL-CS model was updated. We should plan to remove these at some point in the not-too-distant-future. An FRS ticket will be filed.
