Updates from the Fermi-LAT Light Curve Repository

The Fermi-LAT light curve repository (LCR) is a public library of gamma-ray light curves for 1525 Fermi-LAT sources deemed variable in the 4FGL-DR2 catalog. The repository consists of light curves on timescales of days, weeks, and months, generated through a full-likelihood unbinned analysis of the source and surrounding region, providing flux and photon index measurements for each time interval. Hosted at NASA’s FSSC, the library provides users with access to this continually updated light curve data, serving as a resource to the time-domain and multi-messenger communities. Here we provide updates on the current state of the LCR and the variability tools under development in order to exploit these data products.
