Strip:

Strip subtracts a specified fraction of the spectrum. The Strip factor can be “positive“ or

“negative“ :

Spectrum = Spectrum - F*Spectrum

y x

where

Spectrum

- Count content of channel i in the resulting spectrum

Spectrum

- Count content of channel i in the original spectrum

F - Strip factor

Spectrum

- 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.
