The catalogs were built by reprocessing of archival data from the CHArGE compilation, taken by the $\\textit{Hubble Space Telescope}$ ($\\textit{HST}$) in the RELICS, CLASH and Hubble Frontier Fields. Additionally we have reconstructed the $\\textit{Spitzer}$ IRAC 3.6 and 4.5 $\\mu$m mosaics, by utilising all the available archival IRSA/SHA exposures. To alleviate the effect of blending in such a crowded region, we have modelled the $\\textit{Spitzer}$ photometry by convolving the $\\textit{HST}$ detection image with the $\\textit{Spitzer}$ PSF using the novel $\\texttt{golfir}$ software. The final catalogs contain 218,000 sources, covering a combined area of 690 arcmin$^2$. These catalogs will serve as an important tool in aiding the search of the sub-mm galaxies in future ALMA surveys, as well as follow ups of the $\\textit{HST}$ dark - IRAC sources. Coupled with the available $\\textit{HST}$ photometry the addition of the 3.6 and 4.5 $\\mu$m bands will allow us to place a better constraint on photometric redshifts and stellar masses of these objects, thus giving us an opportunity to identify high-redshift candidates for spectroscopic follow ups and answer the important questions regarding the epoch of reionization and formation of first galaxies.","url_abs":"https://arxiv.org/abs/2207.07125v2","url_pdf":"https://arxiv.org/pdf/2207.07125v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"alma-lensing-cluster-survey-hst-and-spitzer","repo_url":"https://github.com/dawn-cph/alcs-clusters","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
