ACD Trending from AcdVetoCal runs

The AcdVetoCal script pulses the charge injection strobe in increasing values of tci_dac and mesures the veto_dac values where the veto line fires
We only fit the curve in the low range (0-23 tci_dac) of the charge injection. We keep track of the following values. Note that the veto_dac step size is about the same as the tci_dac step size. This means that the curves are quite step-like. The test points here are the "CPT" tests list in the full list of ACD test phases
