K2 Variability Catalog ("K2VARCAT")

The lightcurves from K2 contain larger systematics than the original Kepler mission, due to the reduction in pointing precision as a result of having to rely on only two reaction wheels. Armstrong et al. have created a technique to correct for the pointing-dependent nature of the pixel-level fluxes. The team have released their extracted lightcurves (using a photometric aperture defined by the brightness of the target), as well as three plots of the resulting lightcurves: extracted, detrended, and phase-folded. The team has also released a catalog of object classification derived using supervised and unsupervised machine learning.
