Rotation curves and radial 3D velocity dispersion distributions (top), and the radial distribution of stellar particle ages (bottom) of gas-free TDGCs of sample A with the ID 372 and ID 487. The radial bins have a width of 100 pc. The error bars in the bottom panels correspond to the standard deviation of the stellar particle age within a radial bin. The identification number, ID, and their corresponding virial ratios, q (Eq. (C.1)), are given in the panels. The radial density distributions of the TDGCs discussed here are shown in Fig. C.2.
