Notes. Columns 2−4 describe the central star (post-AGB age, luminosity, and effective temperature), and Cols. 5−12 the nebular properties (maximum [O iii]-brightness, rim/shock positions, shock propagation, post-shock velocity, velocities at half-width-half-maximum (HWHM) and half-width-10%-maximum (HW10%M) of the spatially integrated [O iii] 5007 Å line profile, the mean O2+ electron temperature, the mass of the rim, and the total ionised nebular mass). The initial parameters of the circumstellar envelopes are 
M⊙ yr-1 and vagb = 15 km s-1 in all cases.
VHW10%M > Vpost because at this phase of advanced evolution the rim matter expands faster than the shell (cf. top left panel of Fig. 24).
