Spatial mapping of accretion properties in NGC 2264. Small gray dots indicate the distribution of field stars, large dots indicate accreting cluster members. Only objects with an actual Ṁ_acc detection are shown. Symbol colors and sizes are scaled according to the value of Ṁ_acc. The black boxes mark the regions of maximum stellar density in the cluster (from Lamm et al. 2004). Double arrows mark a physical distance of 1.5 parsecs.
