Top panel: rms noise level of the 7M+TM2+TM1 continuum images (in units of 0.1 mJy beam⁻¹ against the spatial resolution (in units of 1000 au)). The dashed horizontal and vertical lines mark the target sensitivity and spatial resolutions of the ALMAGAL project. Bottom panel: Point source mass sensitivity (in units of M_⊙) as function of the spatial resolution as in the top panel. The mass sensitivity is derived from the rms noise level (top panel) assuming a dust temperature of 20 K, a dust opacity of 0.899 cm² g⁻¹ at 1.3 mm, and a gas-to-dust ratio of 100. For most of the ALMAGAL fields, the mass sensitivity is better than the nominal 0.1 M_⊙ aimed in the design of the ALMAGAL project.
