Comparison of line cube and continuum map synthesized beam sizes for the 15 ALMA-IMF fields. (Top panel) Line cube and continuum map synthesized beam sizes are shown in blue and green, respectively. For each field, the average beam size is defined as θ_ave = $\sqrt{{\theta }_{\mathrm{m}\mathrm{a}\mathrm{j}}\times {\theta }_{\mathrm{m}\mathrm{i}\mathrm{n}}}$, where θ_maj and θ_min are expressed in physical scales (au). The horizontal dashed blue and green lines show the median beam sizes for the 15 line cubes and continuum maps, respectively. (Bottom panel) Ratio of the average line cube to continuum map beam size for the 15 ALMA-IMF fields. The horizontal dashed line shows the median.
