ADC_Keywords: Galaxies, photometry Keywords: methods: data analysis - catalogs - galaxies: high redshift - galaxies: photometry Abstract: We present a set of photometric catalogues primarily aimed at providing the community with a comprehensive database for the study of galaxy populations in the high redshift Universe. The set gathers data from eight JWST NIRCam observational programs, targeting the Abell 2744 (GLASS-JWST, UNCOVER, DDT2756 and GO3990), EGS (CEERS), COSMOS and UDS (PRIMER), and GOODS North and South (JADES and NGDEEP) deep fields, for a total area of 0.2 sq. degrees. Photometric estimates are obtained by means of well-established techniques, including tailored improvements designed to enhance the performance on the specific dataset. We also include new measurements from HST archival data, thus collecting 16 bands spanning from 0.44 to 4.44um. Results. A grand total of 530 thousand sources is detected on stacks of NIRCam 3.56 and 4.44um mosaics. We assess the photometric accuracy by comparing fluxes and colours against archival catalogues. We also provide photometric redshift estimates, statistically validated against a large set of robust spectroscopic data. The catalogues are publicly available on the Astrodeep website. Description: We presented and discussed a major release of photometric catalogs, collecting data from eight JWST observational programs on six deep extra-galactic fields. We release a new reduction of the Abell 2744 composite mosaics, gathering the GLASS-JWST, UNCOVER, DDT2756 and GO3990 programs, and use the reductions provided by the teams of the other programs. NIRCam data are complemented with archival HST images on which we perform new measurements. The catalogs, mainly conceived for high redshift science, include a grand-total of 531173 objects, of which 17359 are tagged as spurious, and 2268 more have bad photometric measurements (flag≥400, see Section 3.5). Sources were detected with SExtractor on stacks of the F356W and F444W mosaics of each field. For all the detections we provide positions in equatorial and pixel coordinates, basic morphological parameters, total fluxes and corresponding uncertainties in 16 photometric bands computed by means of the software a-phot, a diagnostic flag, and four photometric redshift estimates obtained with zphot and EAzY. Photometric parameters and photo-z estimates for galaxies in ABELL2744, CEERS, JADES-GN, JADES-GS, NGDEEP, PRIMER-COSMOS and PRIMER-UDS fields The catalogs are publicly available on the Astrodeep website (https://astrodeep.eu).
