LAT 2-year Point Source Catalog Aperture Photometry Lightcurves

Due to a glitch in the analysis pipeline there are apparent increases in flux around MJD 56810 for many sources. These increases are *not* real and should be disregarded. The problem is now believed to be fixed, and the most recent flux measurements are expected to be correct. At a later date the light curves will be reprocessed to remove these incorrect data points.

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.
7. Line number. This will not be present in later versions of these files.

The aperture photometry used:

• 1 degree radius apertures
• 100 MeV to 200 GeV
• IRFs are P7SOURCE_V6 (i.e. event_class = 2)
• 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.
