\caption{Comparison of stellar parameters for HD~37020, HD~37023, HD~37042. The first~values refer to the Cunha \& Lambert (\cite{Cun92}) determinations, the second values to this work. We see that there is excellent agreement for HD~37020, but poor agreement (specially for~\grav) for the other two~stars.}\label{Cunhatable}
