VizieR Online Data Catalog: The first Fermi-LAT >10GeV catalog (1FHL) (Ackermann+, 2013)

The time interval analyzed here is from the beginning of Fermi LAT science operations, 2008 August 4 (MET 239557447) to 2011 August 1 (MET 333849586), covering very nearly 3 yr. In this work we analyze γ rays with energies in the range 10-500 GeV. To limit the contamination from γ rays produced by cosmic-ray interactions in the upper atmosphere, γ rays with zenith angles greater than 105° were excluded. To further reduce the residual γ rays from the upper atmosphere only data for time periods when the spacecraft rocking angle was less than 52° were considered. See section 2 for further explanations.
