The ultraviolet (UV) WFC3 data have been coupled with available WFC/ACS optical-band data. The new CMDs, obtained from the combination of colors coming from eight different bands, disclose an even more complex stellar population than previously identified. This paper discusses the detailed morphology of the CMDs. Description: Multi-band photometric catalog of the ∼35000 inner (∼5'x4') well-measured stars around omega Cen center. All stars in the catalog have a measure in each of the eight band-passes. File Summary:
