Quick-look Pipeline Lightcurves for 9.1 Million Stars Observed over the First Year of the TESS Extended Mission

We present a magnitude-limited set of lightcurves for stars observed over the Transiting Exoplanet Survey Satellite (TESS) Extended Mission, as extracted from full-frame images (FFIs) by MIT's Quick-Look Pipeline (QLP). QLP uses multi-aperture photometry to produce lightcurves for ~1 million stars each 27.4 days sector, which are then searched for exoplanet transits. The per-sector lightcurves for 9.1 million unique targets observed over the first year of the Extended Mission (Sectors 27-39) are available as High-Level Science Products (HLSPs) on the Mikulski Archive for Space Telescopes. As in our TESS Primary Mission QLP HLSP delivery, our available data products include both raw and detrended flux time series for all observed stars brighter than TESS magnitude T = 13.5, providing the community with one of the largest sources of FFI-extracted lightcurves to date.
