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.
| EventNum(evt.Sec)Time | sample | rate (Hz) |

| 300-398(430-526) | Position 1 | 4.7 |
| 400-500 (642-742) | Thorium | |
| 500-600 (860-960) | Position 2 | |
| 600-700 (1070-1170) | Thorium | |
| 700-800 (1290-1390) | Position 3 | 10 |

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");
