Fourth LAT AGN Catalog (4LAC and 4LAC-DR2)
We present the Fourth Catalog of Active Galactic Nuclei detected by the LAT (4LAC) based on 8 years of data. The full description of the catalog is given in this paper. Also available on arXiv. An incremental version of that catalog (4LAC-DR2, for Data Release 2) based on 10 years of data is also available. Its contents is outlined in this document. The data analysis is identical to 4LAC, so the reference is still the 4LAC paper. Please cite both documents when you use the 4LAC-DR2.
