NASA's TESS mission \citeptess has produced high precision photometry of millions of stars to the community. The majority of TESS observations have a duration of ≈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 \citepyield, 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.
