Next: Upper Limits for Up: The Second EGRET Catalog Previous: Primary Catalog . As a result of the re-analysis of the Phase 1 data with the improved model of the diffuse gamma radiation, a number of the sources which appeared in the first EGRET catalog ([ Fichtel et al. 1994b ]) do not appear in this one (and conversely, some in the present catalog would have appeared in the first catalog using the improved model). ... These include 5 of the AGN listed in the first catalog. ...

... Posts tagged ?source matching? ... Without an optical afterglow, a galaxy within the 2 arc second error region of a GRB x-ray afterglow is identified as a host galaxy; however confusion can rise due to the facts that 1. the edge of a galaxy is diffused, 2. multiple sources could exist within 2 arc second error region, 3.the distance between the galaxy and the x-ray afterglow is measured by projection, and 4. lensing causes increase of brightness and position shifts. ...

... The VSOP Survey Continuum Source List . The radio sample for the VSOP continuum survey was defined to include all extragalactic radio sources with: . a total flux density at 5 GHz, S>=1.0 Jy . ... The sample also included all sources in the sky with a 5 GHz flux density S>5 Jy, regardless of spectral index and galactic latitude. ... The source would then be included in the VSOP sample (three of the sources were found with a flux density above 1 Jy and added to the sample). ...
