Location of different icelines in the observed Class 0/I disks derived from the fit intensity profiles at 1.3 mm. Top: location plotted as distance from the center of the disk. Bottom panel: location plotted as the radius of the iceline over the characteristic disk radius r_c. The ‘◃’ and ‘▹’ symbols correspond to upper and lower limits, respectively. The sizes of the symbols are proportional to log₁₀ r_c. The median value for each iceline (ignoring upper/lower limits) is marked with a diamond symbol. The numbers of disks considered for the median is indicated next to diamond marker at the top panel. (See Section 6.3 for more details.
