利用茨维基瞬变设施对北部TESS区的同时观测
Simultaneous observations of the northern TESS sectors by the Zwicky Transient Facility
摘要：
Zwicky Transient Facility（ZTF）正在对2019-2020年所有13个TESS北部部门进行夜间公众调查。ZTF将观察帕洛玛天文台每天晚上可见的当前TESS扇区的部分。每个ZTF指向将分别使用$g$和$r$滤镜进行一次曝光，每晚总计两张图像。ZTF还在对密度较大的恒星区域（例如靠近银道面）进行额外的夜间$g$和$r$波段观测，以更好地促进对银河系天体的变异性研究。ZTF观测的极限星等是$\approx$ 20.6等，ZTF在$\approx$ 13等时饱和。ZTF将以三种形式发布TESS字段中的数据：由已建立的ZTF代理分发的夜间警报，转换为JSON格式的夜间警报通过ZTF在Google Cloud上的桶作为tarball分发，以及每月光度光曲线也通过Google Cloud分发。
英文摘要：
The Zwicky Transient Facility (ZTF) is conducting a nightly public survey of all 13 TESS northern sectors in 2019-2020. ZTF will observe the portions of the current TESS sectors visible from Palomar Observatory each night. Each ZTF pointing will have one exposure each with $g$ and $r$ filters, totaling two images per night. ZTF is also making additional nightly $g$- and $r$-band observations of denser stellar regions (e.g. near the Galactic Plane) to better facilitate variability studies of Galactic objects. The limiting magnitude of the ZTF observations is $\approx$20.6 and ZTF saturates at magnitude $\approx$13. ZTF will release data from TESS fields in three forms: nightly alerts distributed by established ZTF brokers, nightly alerts converted to JSON format are distributed via ZTF's bucket on Google Cloud as a tarball, and monthly photometric light curves also distributed via Google Cloud.
