Three MST clusters identified using d_c = 96″ shown with black group numbers overlaid on the IRAC 8 μm image. The seven subgroups identified by d_c = 40″ are shown with a letter and the cluster number they belong to (see Tables 7 and 8). Massive YSO candidates (M > 8 ﹩{M}_{\odot }﹩) are shown with green crosses. Distributed YSO candidates not assigned to groups are plotted with gray points.
