everest.missions.k2.__init__.CSVHEADER = 'EPIC %09d\n==============\n\n\nDESCRIPTION\n-----------\nDe-trended light curve generated by the Everest pipeline.\nEverest implements 3rd order pixel-level decorrelation to\nremove instrumental systematics from light curves. Here we\nprovide a simple version of the de-trended timeseries, but\nusers are encouraged to interface with the Everest catalog\nusing the Python code available at\n\nhttps://github.com/rodluger/everest\n\nThis is particularly useful for users interested in transit\nphotometry. Like any regression method that attempts to min-\nimize photometric scatter, Everest may partially overfit\ntransit features that are not properly masked. The Everest\ncode provides easy-to-use methods to mask known transits,\neliminating biases in the transit depth. For more informa-\ntion, consult the documentation linked on the github page.\n\n\nATTRIBUTION\n-----------\nIf you make use of this light curve, please cite\n\n 1.
