Luminosity of each [OI]λ6300 component versus the α_IRAC index for all accreting systems. Gray arrows represent upper limits for [OI]λ6300 line luminosities when no emission in [OI]λ6300 was detected. In the HVC plot (right column): light blue arrows represent upper limits for HVC luminosities when only low-velocity [OI]λ6300 emission was detected; blue filled circles represent blueshifted HVCs while red filled circles represent redshifted HVCs (systems that did not present a blueshifted component). Dashed lines represent the boundary between systems with optically thick inner disks (right) and systems with anemic disks (middle), while dashed-dotted lines represent the boundary between systems with anemic disks and naked photospheres, according to α_IRAC (left).
