Is XGPS-25 an extreme ADC source questionMark

Our optical identification campaign of hard Xray sources in the XMMNewtonGalactic Plane Survey (XGPS) has revealed several exceptional objects. Amongthese is XGPS25 which has all the features expected from a lowmass Xraybinary whose Xray emission is strongly shielded by the accretion disc and ifconfirmed, would be the first very high inclination accretion disc corona knownto date. The present proposal aims at obtaining a high quality Xray spectrumand time series which will help us to understand the nature of this object. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
