Velocity slices along the Hα λ6563 and [N II] λ6584 emission-line profiles for: (a) PB 6, (b) M 3-30, (c) Hb 4, (d) IC 1297, (e) Pe 1-1, (f) M 1-32, (g) M 3-15, (h) M 1-25, (i) Hen 2-142, (j) K 2-16, (k) NGC 6578, (l) NGC 6567, (m) NGC 6629, and (n) Sa 3-107, followed by the associated synthetic velocity-resolved channel maps obtained for all the PNs, except for PB 6 and Sa 3-107, produced by the best-fitting morpho-kinematic models with the parameters given in Table 4. Each observed slice has a ∼21 km s⁻¹ width, whose central velocity is given in kilometers per second at the top of the panel. The LSR systemic velocity (v _sys) of each object is given in km s⁻¹ units in the bottom right-hand corner of each observed velocity channel map. The flux color in each observed slice is in logarithm of 10⁻¹⁵ erg s⁻¹ cm⁻² spaxel⁻¹ unit. The gray contour in each panel corresponds to ∼10% of the mean surface brightness of each object in the Hα emission (or R-band) retrieved from the SHS (or SSS). North is up, and east is toward the left-hand side.
