A histogram includes a plurality of channels Ch1, Ch2, . . . ChN, which have respective channel numbers C1, C2, . . . CN. ChA with channel number CA, 1<A<N, representing a first peak, is associated with a known first-peak energy (EA). ChB with channel number CB, 1<B<N, A≠B, representing a second peak, is associated with a known second-peak energy (EB). A system of equations, including a first equation that is a function of EA and CA and a second equation that is a function of EB and CB, is solved for an energy scale, &kgr;, and a zero offset, E0. A function of EM, CM, &kgr;, and E0 is used to identify features in the histogram, wherein EM is an energy associated with the Mth channel in the histogram, and CM is the channel number of the Mth channel (ChM) in the histogram. |
