[OI]λ6300 LVC luminosity versus accretion luminosity. Black diamonds represent our detections, while gray arrows represent our 3σ upper limits to the LVC luminosities when no emission in [OI]λ6300 was detected. Blue squares, purple circles and red crosses represent the values given in R13, N14 and S16 for their samples, respectively. The dashed lines shows a linear fit to the combination of all four samples, including our upper limits.
