The widely-referenced method for obtaining corrected flux values from the raw data of the extended Kepler-K2 mission is described in detail by A. Vanderburg and J. A. Johnson (references below). In the work related to this website, all K2 Campaign-x Corrected Light Curves were downloaded as compressed csv files from A. Vanderburg's website: https://www.cfa.harvard.edu/~avanderb/k2c1/c1corcutlcs.tgz. All uncompressed csv files were converted to Excel plots, 100 at a time, for initial scrutiny using Apple's Automator software followed by an appropriate Excel Macro; the required Automator [ver. 2.1.1 (247.1, 2004-2009)] script was developed by Hank Wade, Computer Technologies Group, Sarasota, FL. Individual corrected light curve data and photometric aperture image plots were also conveniently available from A. Vanderburg's website: https://www.cfa.harvard.edu/~avanderb/allk2c1obs.html.
Mid-transit times (T_c's) and/or mid-eclipse times (E_c's) and their minimum flux values were normally determined using a binomial-fit-model, derivative-zero method; a few were checked with EXOFAST's curve-fitting algorithm (ref. below) and were found to be the same within experimental error.(See, for example, the cases of EPIC-201382958, EPIC-201569483, EPIC-202059433 and EPIC-202060135.) Since very few baselines were flat, depths were calculated as the difference between the flux of the lowest data-point and the "instant baseline" flux [the average flux of the start-of-ingress and the end-of-egress].
Various Eclipsing Binaries and/or Exoplanet Candidates, observed within the K2 mission, are illuminated and partially evaluated on this web-site. Each can be scrutinized by clicking on their GREEN K2C#-# button (page-link) that appear below the column of BLUE KOI-# buttons along the left side of every web-page. One Dwarf Nova (201185922) is also described.
