Moment maps and PV diagram of the [CII] emission line. Top panel: integrated flux, mean velocity map, velocity dispersion map, and continuum-subtracted spectrum of [CII]. The clean beam is plotted in the lower left corner of the moment maps. The cross indicates the peak position of the integrated flux. Bottom panel: PV diagrams of the [CII] emission line along the line of nodes (PA = 275°) and orthogonal to it (PA = 185°).
