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 peak for the Nickel foilI 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");
