Proper motions of the knots in the HH 409 jet. Same as Fig. 2; the dash-dotted lines correspond to the best global fit made to the positions of the knots, with parameters 16.0 ± 0.7 yr and proper motions v_t,red = 0.28 ± 0.01′′ yr^-1, and v_t,blue = 0.49 ± 0.01′′ yr^-1. The A2 data are omitted from the fitting procedure.
