2016 Monthly notices of the Royal Astronomical Society  
Our pipeline uses the Gaussian Process-based K2SC code to correct for the K2 pointing systematics and simultaneously model stellar variability.  ...  All the light curves and code used in the transit search and vetting process are publicly available, as are the follow-up spectra.  ...  We would also like to thank Dave Latham for his helpful comments and his collaboration in TRES followup of our planet candidates.  ...
