EVEREST

EVEREST (EPIC Variability Extraction and Removal for Exoplanet Science Targets) is an open-source pipeline for removing instrumental noise from light curves generated by K2, the repurposed Kepler spacecraft. Operating with only two of four reaction wheels, K2 is unable to maintain the precise pointing precision required to detect the small light modulations caused by transiting exoplanets. EVEREST exploits correlations across the pixels on the Kepler CCD to remove systematics introduced by the spacecraft's pointing error, yielding light curves with precision comparable to that of the originalKepler mission.
