论文摘要
我们提出了高级科学产品（HLSP），其中包含来自MIT的快速管道（QLP）的光曲线，从Tess的第二年扩展任务（Sectors 40-55; 2021年7月至2022年9月）。从10分钟的Cadence全帧图像（FFI）中提取了570万明星的每一扇区光线曲线总共1,220万，并提供给社区。与以前的交付一样，QLP HLSP包括所有观察到的恒星比苔丝幅度t = 13.5 mag更明亮的恒星的原始磁通时间序列。从扇区41开始，QLP还产生了针对精选的M矮人的光曲线。 QLP自tess任务开始以来，迄今为止，QLP为社区提供了FFI提取光曲线的最大来源之一。
We present High-Level Science Products (HLSPs) containing light curves from MIT's Quick-Look Pipeline (QLP) from the second year of TESS' first Extended Mission (Sectors 40 - 55; 2021 July - 2022 September). In total, 12.2 million per-sector light curves for 5.7 million unique stars were extracted from 10-minute cadence Full-Frame Images (FFIs) and are made available to the community. As in previous deliveries, QLP HLSPs include both raw and detrended flux time series for all observed stars brighter than TESS magnitude T = 13.5 mag. Starting in Sector 41, QLP also produces light curves for select fainter M dwarfs. QLP has provided the community with one of the largest sources of FFI-extracted light curves to date since the start of the TESS mission.
