Moment 0 maps of methyl formate obtained toward the ALMA-IMF protoclusters as described in Sect. 3.1. Contours start at 5σ (the 1σ rms noise level is indicated on top of each panel) and double in value thereafter. In each panel the blue crosses show the peak positions of the methyl formate sources extracted with GExt2D, while the green crosses show their associated continuum cores from the getsf-unsmoothed catalog (Paper XII). The blue or white ellipses in each panel represent the synthesized beam of the line cubes.
