TESS Lightcurves From The MIT Quick-Look Pipeline ("QLP")

The Transiting Exoplanet Survey Satellite (TESS) is the first high-precision full-sky photometry survey in space. The MIT QLP team produces light curves from a magnitude limited (TESS magnitude < 13.5) set of stars and other stationary luminous objects from the TESS Full Frame Images (FFIs). The photometric precision roughly follows the theoretical predictions pre-launch. The first data release consists of QLP light curves for targets in Sectors 1-26. These data products cover the two-year TESS Primary Mission and include 14,773,977 and 9,602,103 individual light curve segments in the Southern and Northern hemispheres, respectively. The second data release consists of 10-minute cadence light curves for 9.1 million stars from the first year of the Extended Mission (Sectors 27-39).

凌日系外行星巡天卫星（Transiting Exoplanet Survey Satellite, TESS）是全球首个太空高精度全天测光巡天项目。麻省理工学院QLP团队从TESS全帧图像（Full Frame Images, FFIs）中，为星等限制为TESS星等（TESS magnitude）<13.5的恒星及其他静止发光天体生成光变曲线。其测光精度大致符合发射前的理论预测值。首次数据发布包含扇区1至26的QLP光变曲线，覆盖TESS为期两年的主任务阶段，南半球与北半球分别包含14,773,977条及9,602,103条独立光变曲线片段。第二次数据发布包含扩展任务第一年（扇区27至39）内910万颗恒星的10分钟采样间隔光变曲线。
