论文摘要
Sloan数字天空调查混响映射（SDSS-RM）计划通过光谱和光学图表监视活性银河核（AGN）。在四年中，该工作中使用的光度观察结果为这些对象的可变性研究提供了极好的基线。我们介绍了由管家的BOK望远镜和带有Megacam的CFHT望远镜获得的2014年至2017年的光度光曲线。我们提供了来自每个望远镜的数据采集和处理数据的详细信息，用于生成光曲线的差成像光度法以及计算可变性指数以量化每个AGN的可变性。我们发现Welch-Stetson J-Index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。
The Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) program monitors 849 active galactic nuclei (AGN) both spectroscopically and photometrically. The photometric observations used in this work span over four years 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 CFHT 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.
