Description fermicatsR Author(s) Examples

Since its launch from the Kennedy Space Center on the 11th of June 2008, the Large Area Telescope (LAT, https://www-glast.stanford.edu), on board the Fermi Gamma-ray Space Telescope (formerly GLAST) has been performing an all-sky survey of the gamma-ray sky at energies between 20 MeV and 300 GeV. The LAT Collaboration, consisting of more than 400 scientists at over 90 universities and laboratories in 12 countries, has produced a number of catalogs and lists of gamma-ray sources, at various phases of the mission. The fermicatsR package provides some of these catalogs in the form of the following data sets: FGL0, FGL1, FGL2, FGL3, LAC3_LO, LAC3_HI, FHL1, FHL2, FIG1, and pulsars. For an application of the fermicatsR package, see Saz Parkinson et al., "Classification and Ranking of Fermi LAT Gamma-ray Sources from the 3FGL Catalog using Machine Learning Techniques", The Astrophysical Journal, 820, 8 (2016).

The following is a brief description of the data sets available within the fermicatsR package and their corresponding Fermi LAT catalogs/lists.
