This article provides a wealth of background information on the Kepler project, from the design of the telescope to its planned observational behavior.

New data from the ESA's Gaia spacecraft has provided revised, more accurate stellar radii for all Kepler stars. This has the potential to affect the calculated radius of each KOI, as the radius of a transiting object is equal to the radius of its host star times the square root of the transit depth.

This article provides an excellent insight and source of information on the relationship between eclipsing binaries and the Kepler mission; namely that although the primary mission of Kepler was to detect transiting exoplanets, it also detected many eclipsing binary pairs, which are stars orbiting each other such that they transit one another from our point of view, and which account for many if not most of the false positives that are detected.

This provides a useful summary of the specific False Positive table generated by Dr. Steve Bryson and the False Positive Working Group. It details the concept of a false positive within the context of Kepler, how these false positives were determined, what common causes are, and how frequently they occur.
