Notes. Here, μ – proper motion and its 1σ uncertainty; βapp – apparent speed and its 1σ uncertainty (for K16 only the initial value is given); T – time of ejection and its 1σ uncertainty; Smax – maximum flux density and its 1σ uncertainty; τvar – timescale of flux variability and its 1σ uncertainty; a – average angular size of component and its standard deviation within 0.3 mas from the core for K15 and K16; δ – Doppler factor and its 1σ uncertainty, Γb – Lorentz factor and its 1σ uncertainty; ⟨R⟩ – average distance from the core over epochs presented here and its standard deviation; ⟨Θ⟩ – average position angle of component with respect to the core in projection on the plane of sky and its standard deviation; Θ – angle between velocity vector of component and line of sight and its 1σ uncertainty; N – number of epochs at which component was detected. (*)The parameters of K16 are given for the period when the knot is within 0.5 mas from the core.
