Strip:
Strip subtracts a specified fraction of the spectrum. The Strip factor can be “positive“ or
“negative“ :
Spectrum = Spectrum - F*Spectrum
y
'
y x
where
Spectrum
y
' - Count content of channel i in the resulting spectrum
Spectrum
y
- Count content of channel i in the original 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.
