KEPMAG field is null. , 2MASS - Objects found only in 2MASS Catalog with no optical counterpart, KEPMAG is null, UNCAL - KEPMAG copied from a single color of the parent catalog, uncertainty could be 1.0 mag or higher, PHOTO - parent catalog contained a red and blue mag. obtained from Photographic photometry. Values used to compute KEPMAG on the basis of: sdssg=blue sdssr=red color=sdssg-sdssr if (color<=0.8) kepmag = 0.8*sdssr + 0.2*sdssg else kepmag = 0.9*sdssr+0.1*sdssg, internal photographic errors have errors of 0.2 mag suggest KEPMAG errors of 0.03 mag, TYBV - parent catalog is Tycho-2 and this gives B and V magnitudes. KEPMAG value computed from sdssg=0.54*b+0.46*v-0.07 sdssr=-0.44*b+1.44*v+0.12 using same transformation as above to calc. KEPMAG. Errors same as for TYCHO-2 catalog.

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 the optimal photometric aperture) due to the target star with respect to the total flux from all sources (background flux primarily including that from neighboring stars) in the same aperture. The metric is simulated using a complete end-to-end model of the instrument. It is derived from stellar magnitudes taken from the Kepler Input Catalog. A value of 0.5 means half the light through the aperture is due to the target.
range: 0.0 to 1.0
