Disk substructure detection rates versus the evolutionary stage traced by bolometric temperature. The blue and orange represent the lower and upper limits with the bolometric temperature (T_bol) measured by the eHOPS (with Herschel, but not extinction-corrected) and by Dunham et al. (2015) (no Herschel, but extinction corrected), respectively. The bin size of eight disks was used to compute the substructure detection rates. The shaded region represents the 1σ uncertainty from counting statistics. All 51 protostellar disks are observed by ALMA Band 6 at a wavelength of 1.3 mm, have a disk diameter greater than four times the resolution (θD/θ_res ≥ 4), with an inclination angle of less than 75°, and a linear resolution of less than 20 au.
