EXOSAT observation of 'Geminga'
Abstract
IE 0630 + 178, the X-ray source associated with the gamma-ray source Geminga (2CG195 + 04), has been observed by the EXOSAT satellite. The X-ray images, recorded by the channel-multiple-array instruments at the foci of the two low-energy telescopes equipped with different filters, show clearly the source. The flux value, computed from the count rate after correction for dead time and window transparencies, agrees, within the errors, with the one recorded by the IPC instrument on board the Einstein Observatory.
