Table 5: Comparison of stellar parameters for HD 37020, HD 37023, HD 37042. The first values refer to the Cunha & Lambert (1992) determinations, the second values to this work. We see that there is excellent agreement for HD 37020, but poor agreement (specially for log g) for the other two stars.
Star $T_{\rm eff}$ (K) log g (dex)
HD 37020 29 970/30 000 3.92 / 4.0
HD 37023 32 600/32 000 4.70 / 4.2
HD 37042 31 600/29 000 4.70 / 4.2
