Gamma-ray light curves from statistically limited data; Hercules X-l
Il Nuovo Cimento B(2008)
摘要
Summary The problem of finding the light curve for noisy or sparse data is a familiar one. We develop a model-independent method which
gives the light curve as a linear transformation of the data. Our approach emphasizes the fundamental choices between resolution
and statistical error that is inherent in any data analysis. The analysis is treated as a special case of the general problem
of data analysis based upon Fredholm equations of the first kind. The results, with certain approximations, are formally equivalent
to the kernel density estimators but the interpretation is much different. We apply our technique to a TeV gamma-ray observation
of the X-ray binary Hercules X-l.
