where
Spectrumy ' - Count content of channel i in the resulting spectrum
Spectrumy - Count content of channel i in the original spectrum F - Strip factor
Spectrumx - Count content of channel i in the spectrum to be subtracted
The Energy calibration allows to convert the x-axis channel numbers into energy values in KeV. The following formula is used:
Spectrumy
MCA166-USB
Strip:
Strip subtracts a specified fraction of the spectrum. The Strip factor can be “positive“ or “negative“ :
' = Spectrumy - F*Spectrumx
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.
