The Effect of Non Gaussian Errors on the Determination of Steeply Falling Spectra
msra(2002)
摘要
The determination of a steeply falling energy spectrum from rare events with
non-gaussian measurement errors is a delicate matter. The final shape of the
spectrum may be severely distorted as a consequence of non-gaussian tails in
the energy resolution of the experiment. We illustrate this effect with the
recent experimental efforts to determine the ultra-high energy extreme of the
cosmic ray spectrum.
