ZTF Lightcurves

Zwicky Transient Facility (ZTF) Lightcurves is a catalog of PSF-fit photometry detections extracted from single-exposure images at the locations of ZTF Objects Table detections. An object ID identifies related data in both catalogs. Photometry is in the native ZTF photometric system and the epoch-dependent zeropoints have already been applied. This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.兹威基瞬变设施（Zwicky Transient Facility, ZTF）光变曲线目录是一套收录点扩散函数拟合测光（PSF-fit photometry）探测结果的数据集目录，其数据提取自ZTF天体表探测位置处的单次曝光图像。通过天体ID即可关联两个目录中的相关数据。该测光数据采用ZTF原生测光系统，且已完成随观测时刻变化的零点校正。 本数据集或服务由美国加州理工学院依据与美国国家航空航天局签订的合同，由其运营的IPAC下属红外科学档案（Infrared Science Archive, IRSA）对外提供。
