cds-question@unistra.frglobular-star-clustershst-photometryproper-motionsWe have constructed the most comprehensive catalog of photometry and proper motions ever assembled for a globular cluster (GC). The core of {omega}Cen (NGC 5139) has been imaged over 650 times through WFC3's UVIS and IR channels for the purpose of detector calibration. There exist from 4 to over 60 exposures through each of 26 filters stretching continuously from F225W in the UV to F160W in the infrared. Furthermore, the 11yr baseline between these data and a 2002 ACS survey has allowed us to more than double the proper-motion accuracy and triple the number of well-measured stars compared to our previous groundbreaking effort. This totally unprecedented complete spectral coverage of over 470000 stars within the cluster's core, from the tip of the red giant branch down to the white dwarfs, provides the best astro-photometric observational database yet to understand the multiple-population phenomenon in any GC. In this first paper of the series, we describe in detail the data-reduction processes and deliver the astro-photometric catalog to the astronomical community.2017ApJ...842....6Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/842/6CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)VII/202 : Globular Clusters in the Milky Way (Harris, 1997)J/A+AS/115/297 : BVRI photometry of Central Field of {omega} Cen (Lynga+, 1996)J/ApJ/654/915 : Deep FORS1 BR photometry of omega Cen (Sollima+, 2007)J/ApJ/663/296 : omega Cen (NGC5139) subgiants UBVRIc phot.
