An upper limit to the linear X-ray polarization of Sco X-1.
Abstract
Sco X-1 was observed in a narrow band of X-ray energies centered on 2.6 keV from March 31 to April 10, 1976, with the Ariel 5 satellite Bragg crystal spectrometer/polarimeter. This search for linear X-ray polarization of Sco X-1 produced an upper limit of 7.7 per cent at three-sigma confidence. Modulations in the data which could lead to a spurious measurement of polarization were observed, and are discussed.
