I finally got around to addressing #393 . The plot below illustrates the problem, where the p_sat calculation is thrown-off by an instability in the low-R_tes portion of the IV curve. Note that target bias voltages are not affected by this.
Also, the full P_sat distribution looks like the below. Note all the values between 0 pW and 16 pW
I then made the committed changes to the code, switching the logic from the first time R is above the target r_frac to the last time R is below the target r_frac. This fixed the psat determination in the selected detector, and it also fixed the total psat histogram to get rid of those spurious low values.
Tested on a full UHF UFM in a Princeton test cryosat.
