Spectrometry of faint fast-variable sources in X-ray and gamma astronomy

Creators

Description

Evaluation statistical characteristics of energy spectra parameters at low amount of detected photons from sourse are investigated. Accumulation duration effect on spectrum determination accuracy is investigated for spectral-variable sources. Accumulation time choice methods, minimazing the error, are suggested and studied by statistical simulation
