S\\'ersic profiles are measured for $\\sim$ $26\\,000$ galaxies with stellar masses $M_\\star > 10^9~{\\text{M}}_\\odot$ from JWST/NIRCam F277W and F444W imaging provided by the COSMOS-WEB and PRIMER surveys, using coordinates, redshifts, colors and stellar mass estimates from the COSMOS2020 catalog.
