Results of the fit of the Ca ii IRT NCs velocities.

Parameter NC(A) NC(B)
Vflow (km s−1) 0.67 0.22 + 0.42 $ {}^{+0.42}_{-0.22} $ 0.42 0.51 + 0.34 $ {}^{+0.34}_{-0.51} $
Veq (km s−1) 20.4 ± 9.7 18.8 ± 9.0
ϕs 0.66 0.05 + 0.08 $ {}^{+0.08}_{-0.05} $ 0.01 0.09 + 0.15 $ {}^{+0.15}_{-0.09} $
θ (°) 5.6 3.0 + 69.3 $ {}^{+69.3}_{-3.0} $ 5.0 3.3 + 70.0 $ {}^{+70.0}_{-3.3} $
i (°) 30.1 ± 15.0 30.0 ± 15.0

Notes. Vflow is the velocity of the material in the emitting region, Veq is the equatorial velocity, ϕs is the phase where the emitting region faces the observer, θ is the colatitude of the emitting region, and i is the inclination of the rotation axis.
