GT An observation of a bright nearby radioquiet quasar (PG1211+143) isproposed for XMM GT time. By studying the Fe line profiles (with EPIC) inthese objects, the physics of the accretion disk, and the strong gravityassociated with the supermassive black hole, can be studied. In addition,soft Xray excesses, also perhaps associated with emission or reprocessingfrom the accretion disk, can be explored. In this respect, an important aimwill be to obtain a high quality RGS spectrum of a soft Xray bright,luminous AGN, as a diagnostic of the primary emitting region. Evidence forreprocessing in the RGS band, either through ionised disk reflection orthrough a .warm. absorber will also be important. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
