Radial density distributions of four selected gas-free TDGCs of sample A (IDs 372, 487, 593, and 59553) calculated by the particles identified by the Subfind (blue) and σ-clipping (η = 2 and δ = 0.01; red) algorithms and fitted with a Plummer model (Eq. (C.2)). The radial bins have a width of 100 pc. The identification number, ID, their corresponding virial ratios, q (Eq. (C.1)), and their fitting parameters are given in the panels. The kinetic and potential energy for the Subfind algorithm are taken form Zjupa & Springel (2017) and the calculation for the potential energy using particles identified by σ-clipping assumes a fixed softening length in Eq. (C.11). We note that q is computed solely for the particles selected using Subfind or 2σ-clipping.
