4th Jul 2018: New in lightkurve: identifying time-variable background noise

The new lightkurve open source Python package for Kepler and K2 data analysis, which we first announced in March, contains a new data analysis tutorial which demonstrates how custom aperture photometry can be used to check your target for the presence of time-variable background signals.

The background flux level of …
