Kepler Input Catalog
The Kepler SCP targets were observed by the 2MASS project as well as Sloan filters, such as the griz filters. The catalog alone is not used for finding Kepler targets, because only a portion (about a 1/3 of the catalog) can be observed by the spacecraft. The full catalog includes up to 21 magnitude, giving 13.2 million targets, but of these only about 6.5 to 4.5 million fall on Kepler's sensors.
KIC is one of the few comprehensive star catalogs for a spacecraft's field of view. The KIC was created because no catalog of sufficient depth and information existed for target selection at that time. The catalog includes "mass, radius, effective temperature, log(g), metallicity, and reddening extinction".
Not all star Kepler Input Catalog stars with confirmed planets get a Kepler Object of Interest designation. The reason is that sometimes transit signals are detected by observations not made by Kepler team. An example of one of these objects is Kepler-78b.
