Fig. 20. Offset velocity diagrams in the vicinity of the [OI]A6300, Ha, and He I lines. This figure is taken from [46]. The line profiles are an average of three pixel rows in the spatial direction centered on the continuum. Note that the continuum has not been subtracted. The green dashed lines delineate the ±1 a error envelope for the centroid position of the continuum. The line and continuum centroid errors are the same in all cases. The bipolar offset in the [OI]A6300 reveals the presence of an outflow. No offsets are measured in the Ha and He I lines as expected, ruling out the possibility of spectro-astrometric artifacts s
