With greater sensitivity than any previous IR mission, the James Webb Space Telescope (JWST) will be a powerful tool in future high-redshift IR surveys and follow-up programs. We present Hubble multi-wavelength photometric catalogs, including (up to) 17 filters with the Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) from the ultra-violet (UV) to near-infrared (near-IR) for the Hubble Frontier Fields and associated parallels. We have constructed comprehensive photometric catalogs for four fields and their parallels (MACS 0416, MACS 0717, Abell 2744 and MACS 1149) and are continuing to work on the final two (Abell 1063 and Abell 370; as the data become available). To further expand these data catalogs we have added ultra-deep KS-band imaging at 2.2 μm from the Very Large Telescope (VLT) HAWK-I and Keck-I MOSFIRE instruments. As well as post-cryogenic Spitzer imaging at 3.6 μm and 4.5 μm with the Infrared Array Camera (IRAC). We introduce the public release of the multi-wavelength (0.2—5 μm) photometric catalogs, and we describe the unique steps applied for the construction of these catalogs. Particular emphasis is given to the source detection band and the contamination of light from brightest cluster galaxies and intra-cluster light, and their solution. In addition to the photometric catalogs, we provide catalogs of photometric redshifts and stellar population properties. Furthermore, the public release includes all the images used in the construction of the catalogs, including the combined models of the brightest cluster galaxies and intra-cluster light, the residual models, segmentation maps and more. These catalogs are a robust data set of the Hubble Frontier Fields and will be an important aide in designing future JWST surveys as well as planning follow-up programs to answer key questions remaining about first light, reionisation and the assembly of galaxies, most notably, by identifying high-redshift sources to target with JWST.
