A linear continuum, B, illustrated in Figure 34, is calculated from the sample spectrum
using the equation

Figure 92 Parameters Used in a Linear Continuum Calculation
where
N is the number of channels in the peak ROI, n is the number of continuum channels
evaluated to the left side and the right side of the ROI in determining B
1
and B
2
B
1
is the
sum of counts in the continuum region to the left of the peak, and
B
2
is the sum of counts in the continuum region to the right of the peak.
