Velocity maps. Top, left to right: the absolute line-core velocity of Fe i 630.25 nm line, line-core velocity of Si i 1082.7 nm line retrieved via SIR inversion, and Ca ii H center-of-gravity velocity. Bottom, left to right: Hα, Ca ii IR line-core, and He i 1083 nm line-core velocity obtained by the HeLIx+ inversion. The center-of-gravity velocity of Ca ii H line was calculated for a spectral range of 100 pm around the line core. All velocities are in km s^-1.
