TESS as a Low-surface-brightness Observatory: Cutouts from Wide-area Coadded Images

Yet over spatial scales of a few degrees, the background appears uniform. This result indicates that TESS has considerab...

Zusammenfassung:We present a mosaic of those co-added Full Frame Images acquired by the TESS satellite that had been released in 2020 April. The mosaic shows substantial stray light over the sky. Yet over spatial scales of a few degrees, the background appears uniform. This result indicates that TESS has considerable potential as a Low Surface Brightness Observatory. The co-added images are freely available as a High Level Science Product (HLSP) at MAST and accessible through a Jupyter Notebook.
