Taking into account the range of spatial distribution models which are consistent with the data, we derive a flux of 9.9(+4.7;-2.1) x 10-4 ph cm-2 s-1 and an intrinsic line width of 2.95(+0.45;-0.51) keV (FWHM). The results are consistent with other high-spectroscopy measurements, though the width is found to be at the upper bound of previously reported values.\nBased on observations with INTEGRAL, an ESA project with instruments and science data centre funded by ESA member states (especially the PI countries: Denmark, France, Germany, Italy, Switzerland, Spain), Czech Republic and Poland, and with the participation of Russia and the USA. \n" . @prefix istituto: . prodotto:ID5593 prodottidellaricerca:prodottoDi istituto:CDS005 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA3700 . istituto:CDS005 prodottidellaricerca:prodotto prodotto:ID5593 .
