Evolution of disk fraction with time: the top panel is the 24 μm disk fraction, and the bottom panel is the 70 μm disk fraction. Values from the literature (see Table 5) are compared with our values for the BPMG. Literature 24 μm points are circles, the BPMG 24 μm point is a large solid five‐pointed star, literature 70 μm points are boxes, and the BPMG 70 μm point is a large solid box. The gray vertical lines are the errors calculated from Poisson (counting) statistics. Our points are consistent with the disk fractions for similarly aged clusters and associations found in the literature.
