The first row shows moment maps of the Meerkat-64 observations, the second row shows our combined two-component model which reproduces most of the features in the observed moment maps, the bottom row shows the residuals from the subtraction of the two. The contours of moment-0 map correspond to the ticks of the colourbar. The contours on the moment-1 map correspond to a velocity range between −40 and 40 km s⁻¹ with a spacing of 5 km s⁻¹ and for the moment-2 map they correspond to 6,8,10,12 and 14 km s⁻¹, respectively.
