Moment maps showing the comparison between the data and the BBarolo best fit performed on the Big region around NED01. Shown (from left to right) are data, BBarolo model, and residual emission. The rows show (rom top to bottom) the moment 0 map (intensity), moment 1 map (line of sight velocity), and moment 2 map (velocity dispersion). The black cross indicates the rotating disk centre found by the fit, and the dashed black line shows the major axis of the disk model.
