All of the files used for calibration are contained in the path /data/IAC/Calibration/10-28-2016

Using the root commands

.L TempVoltageFit.C

TempVoltageFit(0,2);

Yields

a = -25.2552 b = 0.95302

So the command to draw the spectrum in root is

MPA->Draw("-25.2552+0.95302*evt.Chan>> SeRun_008(8000,0.5,8000.5)");

Which produces the spectrum
