Off-Peak Statistics

The Off-Peak Statistics button is used to calculate a statistically equivalent off-peak counting time for the background position integration measurement. The parameters required for the calculation are the on-peak count time, the on-peak count rate (cps) and the off-peak count rate (cps). The calculated off-peak count time is divided between the two off-peak positions when the user clicks the Apply button. The calculation is from Scott and Love, 1983.

 

                   where:          tB = calculated background count time

                             tP = on-peak count time

                   IB = off-peak intensity

                             IP = on-peak intensity
