Despite the fact that the source is currently more than 35 degrees off-axis, a preliminary maximum likelihood analysis shows a detection at a significance level of about 9 sigma, with a source flux in excess of 100e-8 ph/cm2/s at energies above 100 MeV.Gamma RayAGNhttp://adsabs.harvard.edu/abs/2008ATel.1545....1D2008ATel.1545....1D
