    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.
