Notes. The Gaussian amplitudes are normalised to the sum of the amplitudes. The main beam parameters are identified with the index 1, while the two error beams are presented with the subscripts 2a and 2b. The FWHMeff are the effective full width at half maximum of a single elliptical Gaussian. The beam surface area is derived from the best-fit parameters. These results are represented as red dashed lines in the average beam patterns of CONCERTO in Fig. 3.
