As Fig. 3, but now for: this work (filled triangles, and the stars without excess as crosses), other data based on SED modelling: 47 Tuc (filled squares), ω Cen (filled circles), NGC 362 (filled stars), and modelling of chromospheric lines: M13 (open stars), M15 (open diamonds), M92 (open triangles), and ω Cen (open circles). The fit is to the present sample and the mass-loss rates from modelling the chromospheric lines, while the dashed line represents Reimers law with η = 0.35. The cross in the lower right corner indicates a typical error bar.
