The Rate column values were estimates of the rate in a single channel (1376 keV ) observed online during data acquisition. The rates in the graph above were from an offline analysis integrating over about 20 channels around the 1376 keV peak.

Calibration

MPA->Draw("evt.Chan*(0.490) >>(6096,0,6096)","evt.Sec > 690 && evt.Sec < 1000");


A clear 583 keV peak can be seen for the Thorium rod runs using the command

MPA->Draw("evt.Chan*(0.490) >>(40,560,600)","evt.Sec > 642 && evt.Sec < 742");

There is no 583 keV peak for the Nickel foil.

I do see a 1376 keV line characteristic of the Nickel foil in the Thorium rod spectrum

MPA->Draw("evt.Chan*(0.490) >>(40,1360,1400)","evt.Sec > 1070 && evt.Sec < 1170");
