New in Lightkurve: interactively selecting pixel aperture masks

Kepler data analyses often begin with establishing which pixels your target of interest occupied, and to what extent artifacts or background signals affect those pixels. The Kepler/K2 in-house toolkit, Lightkurve, offers a new mechanism to witness — in real time — the differential impact of aperture mask pixel selection on the …
