A magnitude computed according to a hierarchical scheme and depends on what pre-existing catalog source is available, SCP, Tycho 2, or photographic photometry, in order of preferred selection. For SCP stars the magnitude is synthesized from the Sloan-like g and r magnitudes according to the following prescription: if one defines 'color' as g - r, then for color less than or equal to 0.8 kepmag = 0.8r + 0.2g, while for color greater than 0.8 kepmag = 0.9r + 0.1g.

Skygroup_ID

An integer value from 1 to 84 describing the module/channel where the target falls. It's equivalent to the channel number during season 2. The sky group is an integer that groups stars together on the sky depending on which channel they fall on (or near) during season 2. Due to slight asymmetries in the CCD array layout, positions are not perfectly maintainted upon seasonal rotation of the spacecraft. Therefore, there are objects that fall off silicon during season 2 but are on silicon in subsequent seasons. This is especially problematic for Module 13 due to the center gap. Such stars are assigned the sky group corresponding to the other stars that fall on the same channel during other seasons.
range: 1 - 84

Crowding value

The crowding metric is a number between 0 and 1 that specifies the fraction of flux (in a 21x21 pixel aperture centered on the target) due to the target star with respect to the total flux from all sources in the same aperture. A value of 0.5 means half of the light through the aperture is due to the target. The crowding values are intended only to facilitate the selection of isolated stars as targets. The crowding values are NOT suited to correct flux light curves and such analysis will most likely lead to INCORRECT results.

The 21x21 pixel aperture used to calculate the crowding value is not the same as the photometric aperture used to create the Kepler flux light curves. The true crowding relevant to the flux light curve can be substantially different and varies from season to season because of changes in photometric aperture size, the pixel response function, optical throughput, and other position-dependent characteristics of the focal plane.

range: 0.0 to 1.0

Seasons_on_CCD

Number of seasons a target is on the detector
range 1 to 4 and null (note: roughly 30% of the targets were included because they are near the edge)

Contamination

Measure of light contamination defined as 1 - crowding_value. A value of 0 implies no contamination, 1 implies all background. The contamination values were calculated using a 21x21 pixel aperture centered on the target. The contamination values are intended only to facilitate the selection of isolated stars as targets. They are NOT suited to correct flux light curves and such analysis will lead to INCORRECT results.

The 21x21 pixel aperture used to calculate the contamination value is not the same as the photometric aperture used to create the Kepler flux light curves. The true crowding relevant to the flux light curve can be substantially different and varies from season to season because of changes in photometric aperture size, the pixel response function, optical throughput, and other position-dependent characteristics of the focal plane.
