Based on the first 4yr     of science data from the Fermi Gamma-ray Space Telescope mission, it     is the deepest yet in this energy range. Relative to the Second Fermi     LAT catalog, the 3FGL catalog incorporates twice as much data, as well     as a number of analysis improvements, including improved calibrations     at the event reconstruction level, an updated model for Galactic     diffuse γ-ray emission, a refined procedure for source     detection, and improved methods for associating LAT sources with     potential counterparts at other wavelengths. The 3FGL catalog includes     3033 sources above 4σ significance, with source location     regions, spectral properties, and monthly light curves for each. Of     these, 78 are flagged as potentially being due to imperfections in the     model for Galactic diffuse emission. Twenty-five sources are modeled     explicitly as spatially extended, and overall 238 sources are     considered as identified based on angular extent or correlated     variability (periodic or otherwise) observed at other wavelengths. For     1010 sources we have not found plausible counterparts at other     wavelengths. More than 1100 of the identified or associated sources     are active galaxies of the blazar class; several other classes of     non-blazar active galaxies are also represented in the 3FGL. Pulsars     represent the largest Galactic source class. From source counts of     Galactic sources we estimate that the contribution of unresolved     sources to the Galactic diffuse emission is ∼3% at 1GeV. Description:     The data for the 3FGL catalog were taken during the period from 2008     August 4 (15:43 UTC) to 2012 July 31 (22:46 UTC), to covering close to     4yr. The LAT detects γ-rays in the energy range from 20MeV to     more than 300GeV. File Summary:        FileName      Lrecl  Records   Explanations ReadMe            80        .
