The error calculation is based on the following assumption:
the mean systematic error owing to the background fit polynomial
can be neglected, when compared with the statistical fluctuations.
Since the typical mean count rate varies in the range from 800-1200 counts/s,
it turns out that
counts/s; we confidently
estimate that the error introduced within the background subtraction
is dominated by the statistical uncertainties.
Therefore, from eq.
, the only term
contributing to the uncertainties on the total counts estimates
is the measured counts of every bin, according to the
eq.
.
