- Count content of channel i in the resulting spectrum
Spectrum

F - Strip factor
Spectrum
x
- Count content of channel i in the spectrum to be subtracted
E-calibration:
The Energy calibration allows to convert the x-axis channel numbers into energy values
in KeV. The following formula is used:
E = S Channel + O
where,
S - Slope
O - Offset
The coefficients can be set as numeric values or by linear fit of two energy
channel/peak centroid pairs.
