Wavelet coefficient maps of regions 01a (top), 21a (middle) and all stars studied in this work (bottom) retrieved in (left column) and (right column) space for scale J = 2. Colour bars show normalised wavelet coefficients. Black crosses show centres of the structures. Boxes around the crosses show location of kinematic structures based on the nearby sample 00 (see Fig. 3). Colours of the boxes correspond to different names of the structures listed in the legend of Fig. 3.
