Assessment of Kepler Dataset

A unique feature of the seventh Kepler candidate catalog is that it is the first to fully automate the assessment of transit-like signals. The total height of each bar shows the total number of Kepler Objects of Interest (KOIs), or transit-like signals, in each catalog. The blue area shows the number that was assessed, which includes all newly found KOIs. The grey area shows the number that were not able to be assessed due to time constraints imposed by manual assessment, which includes KOIs assessed in previous catalogs. As a result of the new automated procedures employed in this seventh catalog, all KOIs could be assessed. The resulting impact is that we are able to deliver a more uniform planet candidate catalog that utilizes the entire Kepler dataset, which will enable more accurate estimates of the number of small habitable zone planets in our galaxy.
