There was a bug in the code computing the surface gravity, for stars with [FORMULA] K. This implied a slight overestimate of [FORMULA], by up to 0.15 dex, and affected part of Table 1, Fig. 1, 2 and 4. All other quantities ([FORMULA]) were unaffected, but the estimated errors on [FORMULA] were slightly biased. The corrected Table and Figures are reproduced below (the whole Table is reproduced although 26 lines were free of error).

In the text (Subsection 2.3), the scatter of the residuals around the regression line of Fig. 1 (left panel) is [FORMULA] dex (instead of 0.273). In Subsection 2.4, the [FORMULA] values quoted for HD 24155, HD 142884 and HD 221006 should read [FORMULA] 4.34, 4.54 and 4.38 respectively (instead of 4.48, 4.67 and 4.51). Furthermore, the discussion about HD 221006 overlooked the recent determination of its projected rotational velocity [FORMULA] km s-1 by Leone et al. (1995), as Dr. Leone kindly pointed out to me; taking this result into account brings HD 221006 just below the equality line in Fig. 3 and nicely reconciles its [FORMULA] with radius and period.

In Sect. 3, the surface gravities of CU Vir should read [FORMULA] for [FORMULA] K (instead of [FORMULA]) and [FORMULA] for [FORMULA] K (instead of [FORMULA]).

The discussion and conclusion remain essentially unaffected.
