论文摘要
苔丝（Tess）（过境系外行星调查卫星）于2018年启动，目的是观察太阳能社区中的明亮恒星，以寻找过境的系外行星。在完成两年的名义任务后，TESS提供了2 \ 200千颗星的2 \微小节奏光度法。大量的光曲线收集了研究恒星集合的统计和时间特性的可能性。 大多数当前可用的数据管道旨在一次在单个部门上使用。我们提出了一个称为{\ tt taranga}的新苔丝数据管道，目的是合并多扇区光曲线，同时对所有观察到的恒星进行期间搜索，并将统计结果存储在数据库中。 {\ tt taranga}管道具有三个组件，其中1）处理每个扇区的PDCSAP通量，并创建合并的PDCSAP光曲线，2）在SAP通量上执行类似的操作，3）生成合并的SAP和PDCSAP光曲线的周期性图，同时识别合并的SAP和PDCSAP光曲线。 对于所有232 \，在标称苔丝任务中短暂观察到的122颗恒星，我们提供合并的PDCSAP和SAP灯曲线及其周期图。我们提供了一个数据库，该数据库具有这些恒星{\ tt taranga}产生的所有结果的统计信息。
TESS (Transiting Exoplanet Survey Satellite) was launched in 2018 with the purpose of observing bright stars in the solar neighbourhood to search for transiting exoplanets. After the completion of the two year nominal mission, TESS has provided 2\,minute cadence photometry of over 200\,000 stars. This large collection of light curves opens the possibility to study the statistical and temporal properties of this ensemble of stars. Most of the currently available data pipelines are designed to work on single sector at a time. We present a new TESS data pipeline called {\tt Taranga}, with the purpose of merging multi-sector light curves, whilst performing a period search for all the observed stars, and stores the statistical results in a database. {\tt Taranga} pipeline has three components which 1) processes the PDCSAP fluxes of each sector and creates merged PDCSAP light curve, 2) performs a similar operation on the SAP fluxes, and 3) generates the periodograms of the merged SAP and PDCSAP light curves while performing peak identification. For all the 232\,122 stars observed in short cadence in the nominal TESS mission, we provide the merged PDCSAP and SAP light-curves along with their periodograms. We provide a database that has the statistics of all the results produced from {\tt Taranga} of these stars.
