$O_i^{\rm obs}$ : $\mathscr M_1=4.04\pm0.11$ ; $\mathscr R_1=3.77\pm0.03$ ; $T_{\rm eff~ 1}=13140\pm1500$ ; $q=0.674\pm0.009$ ; $k=0.541\pm0.013$ ; $\Delta T_{\rm eff}=1096\pm100$ (or $1240\pm100$ , see text).
For all models OV₁=0. Model AC belongs both to group A and C. Several C-type models are listed to illustrate the effect of adjusting OV₂.
