NASA的TESS使命\citep{tess}为社会提供了数百万颗恒星的高精度测光。大多数TESS观测的持续时间约为27天，对应于TESS扇区期间的单个观测。TESS目标的一个小子集被观察到多个扇区，在主要使命\citep{yield}期间，大约1- 2%的目标落入连续观察区（CVZ），其中目标被连续观察一年。这些目标是非常有价值的提取长周期的旋转速率，这可以与恒星的年龄。我们提出了一个pip可安装的Python工具，用于提取TESS CVZ中的长周期旋转速率，同时减轻仪器系统性。
NASA's TESS mission \citep{tess} has produced high precision photometry of millions of stars to the community. The majority of TESS observations have a duration of $\approx$27 days, corresponding to a single observation during a TESS sector. A small subset of TESS targets are observed for multiple sectors, with approximately 1-2\% of targets falling in the Continuous Viewing Zone (CVZ) during the prime mission \citep{yield}, where targets are observed continuously for a year. These targets are highly valuable for extracting long period rotation rates, which can be linked to stellar ages. We present a pip installable Python tool for extracting long period rotation rates in the TESS CVZ, while simultaneously mitigating instrument systematics.
