An example of how the ALMA processing affects the data. Panels (a) and (b) show an ∼700 pc area of the face-on galaxy observed with high and low resolutions (PPV|$\mathrm{_{face}^{H}}$| and PPV|$\mathrm{_{face}^{L}}$|⁠), respectively. Beam size (∼24 pc) of low resolution is shown in panel (b) with black filled circle. Centres of mass of GMCs are marked with black or white crosses. It is clear that because of the low resolution or/and sensitivity in our setup, the small clouds in the high-resolution data disappear in the low-resolution data. Moreover, clouds become more spherical in panel (b) due to the image convolution with the circular beam.
