Comparison of different rms noise level estimates for the final ALMAGAL 7M+TM2+TM1 continuum images. The noise is calculated as the standard deviation of the residual image (AG-STD-RES) as a function of the noise calculated as the median absolute deviation of the residual image (AG-MAD-RES). The black dashed lines corresponds to y = x, while the red dotted line corresponds to y = 1.45 x (i.e., the rms noise level estimated with the standard deviation is about 45% larger compared to the median absolute deviation estimate).
