论文摘要
提出了Fermi-Lat检测到的活性银河核（AGN）的第四目录的增量版本（4LAC-DR2）。此版本与4FGL通用目录的第二版（基于10年的数据）相关联，其中光谱参数，光谱能量分布，年度光曲线和关联已更新了所有来源。新报道的AGN包括两个射电星系和283个Blazars。我们简要描述了新样本的属性和概述变化，影响了先前发表的样本。注意：此增量版本的用户被要求引用原始的4LAC纸（Ajello M.等，2020，APJ，892，105）。
An incremental version (4LAC-DR2) of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT is presented. This version is associated with the second release of the 4FGL general catalog (based on 10 years of data), where the spectral parameters, spectral energy distributions, yearly light curves, and associations have been updated for all sources. The new reported AGNs include two radio galaxies and 283 blazars. We briefly describe the properties of the new sample and outline changes affecting the previously published sample. Note: Users of this incremental release are requested to cite the original 4LAC paper (Ajello M. et al., 2020, ApJ, 892, 105).
