Cumulative radial profiles of the CONCERTO beam for the low-frequency (top) and high-frequency (bottom) arrays during the 2021 and 2022 campaigns. These profiles were derived from the normalised combination of 13 and 15 beam-map scans on planets. The dashed line represents the best-fit profile model integrated with the radius. The dotted lines represent cumulatively each Gaussian component, the main beam (lowest) and the first error beam.
