LAT 4FGL-DR2 Catalog Aperture Photometry Lightcurves

We provide here aperture photometry light curves of all sources in the Fermi Large Area Telescope 10-year Source Catalog (4FGL-DR2) with 30 day time resolution. The light curves and plots will generally be updated weekly. We also plot power spectra of the light curves for periods between 65 days and the length of the light curve, with a frequency oversampling of a factor of 5.

Some caveats:

• These light curves are intended to provide a quick way to inspect gross features in the long-term light curves. They are unlikely to be directly useful for detailed scientific analysis.
• They are not background subtracted.
• The apertures will contain photons from nearby sources.

A thread describing the steps involved in aperture photometry of LAT data can be found here. A script to perform aperture photometry (aperture.pl) is available here.

The columns in the data files are:

1. Time of center of bin (MJD)
2. Count rate in the aperture in photons cm^-2 s^-1
3. Count rate error based on the observed number of photons. This is used in the plots
4. Half-width of the time bin in days.
5. Count rate error based on the relative exposure of the time bin.
6. Exposure in cm^2 s.

The aperture photometry used:

• 1 degree radius apertures
• 100 MeV to 200 GeV
• Data are P8 Source class (evclass=128), front+back (evtype=3)
• A zenith limit of 105 degrees.
• A rock limit of 90 degrees. (i.e. no filtering on this.)
• A bore-sight limit of 180 degrees. (i.e. no filtering on this.)
• Times when a source was closer than 5 degrees from the Sun are excluded.

For caveats on period detection in LAT light curves please see here.
