Spectro-astrometric analysis of the [O i] λ6300 and Hα lines. Offsets are measured using Gaussian fitting. The black asteriks are the offsets measured after continuum subtraction. The accuracy in the measurement of the offsets is ~20 mas. This analysis confims that the [O i] λ6300 line is tracing the outflow while no outflow component is detected in the Hα line.
