Distribution of the noise level (left column), peak intensity (central column), and dynamic range (right column) for the continuum ALMAGAL images. The y-axis in all panels depicts the number of images. From top to bottom, each row corresponds to the images for the 7M, TM2, TM1, 7M+TM2, and 7M+TM2+TM1 array configurations. The dynamic range (or signal-to-noise ratio) is determined as the ratio between the peak intensity and the noise level, with the noise level derived as the median absolute deviation (MAD) of the residual image (see Sect. 4.5.3).
