Ratio of measured to predicted 70 μm flux as a function of time for objects in the literature, as described in the text; gray times symbols or upper limits correspond to our objects from the BPMG and Tuc‐Hor. The horizontal dotted line corresponds to the ﹩F_{\mathrm{meas}\,}/ F_{\mathrm{pred}\,}=2﹩ cutoff between disks and photospheres discussed in § 3.2.
