IRAM 30 m full kernel for the error beam contribution analysis after deconvolution of the main beam, G0, for 3 mm. The kernel includes the three components of the error beam ( indicates the Gaussian 2D profile after deconvolution with G0). The ratio of the relative beam power with respect to the relative main beam power (P0) is indicated by ϵi = Pi/P0.
