The Sloan Digital Sky Survey (SDSS) Reverberation Mapping program monitors 849 active galactic nuclei (AGNs) both spectroscopically and photometrically. The photometric observations used in this work span over 4 yr and provide an excellent baseline for variability studies of these objects. We present the photometric light curves from 2014 to 2017 obtained by the Steward Observatory’s Bok telescope and the Canada–France–Hawaii telescope with MegaCam. We provide details on the data acquisition and processing of the data from each telescope, the difference imaging photometry used to produce the light curves, and the calculation of a variability index to quantify each AGN’s variability. We find that the Welch–Stetson J index provides a useful characterization of AGN variability and can be used to select AGNs for further study.

Sloan数字天空测量混响测绘项目:光度g和i光曲线

斯隆数字天空测量(SDSS)混响映射程序可以通过光谱学和光度学方法监视849个活动银河核(AGN)。在这项工作中使用的光度学观测跨越了4年,为这些物体的变异性研究提供了极好的基线。我们介绍了2014年至2017年由Steward天文台的Bok望远镜和带有MegaCam的加拿大-法国-夏威夷望远镜获得的光度学光曲线。我们提供有关每个望远镜的数据采集和处理,用于产生光曲线的差值成像光度法以及计算可变性指数以量化每个AGN可变性的详细信息。我们发现,Welch–Stetson J指数提供了AGN变异性的有用表征,可用于选择AGN进行进一步研究。
