The recent release of the GALEX Release 6 dataset includes 72 sky "tiles" overlapping some 60% of the Kepler Field of View. MAST (Multi-Mission Archive at Space Telescope Science Institute) has constructed a cross-match catalog of all matches of GALEX objects with 5" of the coordinates for objects in the Kepler Input Catalog (KIC) and vice-versa.
The results permit the addition of UV colors (near-UV and/or far-UV, centered at about 2300 Angstroms and 1500 Angstroms, respectively) to
the SDSS program's griz filters that the Kepler ground-based support photometric program emulated. Until now the absence of an ultraviolet filter for this ground survey of KIC objects has meant that it was not possible to clearly identify hot (OBA-type) objects. The addition of the GALEX UV magnitudes will address this deficiency. In addition, the (FUV-NUV) vectors for ISM reddening and stellar temperature are very different, allowing the former degeneracy of the two terms to be lifted. We exhibit on-line tools to enable users to obtain UV, griz, and 2MASS colors to aid in the search of targets and to investigate general distributions of objects in the KIC. We discuss completeness of the cross-match survey with the KIC catalog. We point out that the numbers of detections are primarily limited by the far-UV and near-UV effective apertures of GALEX.
