MCA527 Algorithm, Formulas
Strip:
Strip subtracts a specified fraction of the spectrum. The Strip factor can be “positive“ or “negative“ :
where
Spectrum
y
' = Count content of channel i in the resulting spectrum
Spectrum
Y
= Count content of channel i in the original spectrum
Spectrum
x
= Count content of channel i in the spectrum to be subtracted
F = Strip factor
E-calibration:
The Energy calibration allows to convert the x-axis channel numbers into energy values in KeV. The following
formula is used:
where
S = slope
O = offset
Channel = channel number
The coefficients can be set as numeric values or by linear fit of two energy channel/peak centroid pairs.
