fermicatsR (v 1.4): A package containing catalogs from the Fermi Large Area Telescope.

Description

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.

For more details on any of these data sets, type 'help(dataset)' or go to the Fermi Science Support Center (FSSC) web page (http://fermi.gsfc.nasa.gov/ssc/data/access/). You can also contact me directly with your questions.

Examples

# Variability index vs Curvature significance of 2FGL sources, color-coded by source class
data(FGL2)
if (require("ggplot2")) {
qplot(log(Signif_Curve), log(Variability_Index), data = FGL2, color = CLASS1)
}
# Distribution of spindown luminosities of LAT-detected gamma-ray pulsars
data(pulsars)
hist(log10(pulsars$Edot), 
xlab = "Log(Spindown Luminosity) (erg/s)", 
ylab = "Number of pulsars", 
main = "LAT-Detected Gamma-ray Pulsars")
