The referee, Dr. F. Castelli, is thanked for her constructive comments on the original manuscript. We thank N.Y. Rogers, UCLA, for his calculation of many models and their uvby colours, F. Castelli for providing the modified mixing-length ATLAS9 colours (MLT OV) and R.L. Kurucz for his permission to use ATLAS9 and related software and data. F. Kupka is grateful to V. M. Canuto for many discussions on turbulence theory and the CM model. This research was done within the project Asteroseismology-AMS. Models and fluxes were calculated on an Alphastation 200 4/233 funded from the DEC-EERP project STARPULS, and on an Alphastation 250 4/266, funded through the Fonds zur Förderung der wissenschaftlichen Forschung (project S7303-AST), who also supported F. Kupka during work on this project. This work has made use of the hardware provided at Keele by the PPARC Starlink Project and NASA's Astrophysics Data System Abstract Service.
