Paper Abstract

Scattering from bound electrons in a suitable material placed at the focus of an x-ray telescope can be exploited to measure the linear polarization of radiation emitted from cosmic x-ray sources. Among the factors that affect the performance of such an instrument is a spurious polarization signal from unpolarized sources that lie within the field of view but are offset from the telescope pointing direction. In this paper we present the results of analytical and Monte Carlo studies of this effect and provide means of evaluating its impact on realistic polarimeters for x-ray astronomy.
