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

Run File Isotope Photon Energy (keV) Channel
Cs-137-10-028.root Cs-137 661.657 721 +/- 0.9616
Co-60-10-028.root Co-60 1173.2 1268 +/- 1.35
Co-60-10-028.root Co-60 1332.5 1439 +/- 1.435
Na-22-10-029.root Na-22 511 560 +/- 1.481
Na-22-10-029.root Na-22 1274.537 1337 +/- 1.371
Mn-54-10-028.root Mn-54 834.848 2054 +/- 1.657

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
