We report here the variation in the width per fiber in each region composing the EMERGE Early ALMA Survey. The fibers are numbered based on their identification number (ID) and we display the range within minimum and maximum width per fiber with colour-coded areas. The solid black lines represent the median width per fiber, while the dashed lines the median width per region (e.g. circles displayed in Fig. 6). The lower rightmost panel shows the distribution of all the 991 cuts fitted in our sample (see also Fig. 4, left panel).
