Plot of ﹩K_{s}-[ 24] ﹩ vs. ﹩K_{s}-[ 70] ﹩ for all of the objects considered here. Plus signs are objects detected (at 70 μm) from the BPMG; open circles are detected objects from Tuc‐Hor. All other objects (from both associations) are indicated as upper limits at 70 μm. These results are consistent with an "inside‐out" infrared excess reduction scenario, where 24 μm excesses disappear before 70 μm excesses; see text for further discussion.
