Left: subclusters identified in the G305 star-forming region (using ﹩{d}_{c}=30^{\prime\prime} ﹩) are overlaid on the IRAC 5.8 μm image. Right: subclusters identified in the G333 star-forming region (using ﹩{d}_{c}﹩ = 52″) are overlaid on the IRAC 5.8 μm image. Distributed YSO candidates not assigned to groups are plotted with gray points.
