Fluxes are in the unit of photons/cm^2/s above 100 MeV. All uncertainties are
statistical only.
Note. All the flux reported above are by the ASP analysis and should be
considered preliminary and should not be used for publication, however they are
indicative of the flux range and the current status of a source. Source
association is done on the basis of source location, considering spatial
coincidence only, and it is not indicative of an identification.
