to draw a histogram for Peak ADC channel 4

PAA->Draw("PADC.PADC785N[4]>>(4096,0,4096)")

To scale the histogram using an energy calibration of 0.45 keV/channel

PAA->Draw("PADC.PADC785N[4]*0.45>>(4096,0,4096)")

To save thehistogram under the name Cs137

PAA->Draw("PADC.PADC785N[4]*0.45>>Cs137(4096,0,4096)")

To normalize the histogram by a run time of 2600 seconds

1/3600=0.0002778

Cs137->Scale(0.0002778)
Cs137->Draw();
