Looks like a logarithmic current dependence for IC 1, but otherwise smooth. Similar scaling factors and thresholds to previous settings.

The cavity tripped on 6/13 during day/swing and they couldn't recover it, tried to step it off but discovered the tuner wasn't working to detune it. It has been GSET0 since, but was draining pretty heavily.

I managed to recover it back at 11 MV/m. A thing to remember for high gradient C25s is that the lorentz force detuning effects may prevent you from actually turning the cavity back on at 4 MV/m, so contrary to what we may think, trying closer to 8 MV/m may end up working.

We can see this in the plot of GMES, TDETA, and CRFP as I was finding a good spot to recover it.
