-    "The [`Lightkurve` package](https://docs.lightkurve.org) provides a large amount of complementary functionality to stingray, in particular for data observed with Kepler and TESS, stars and exoplanets, and unevenly sampled data. We have implemented a conversion method that converts to/from `stingray`'s native `Lightcurve` object and `Lightkurve`'s native `LightCurve` object. Equivalent functionality exists in `Lightkurve`, too. "
