Table 1: Parameter space used for the models and the astrophysical parameters of the standard star Vega and the $\lambda$ Bootis stars HD 107233 and HD 204041.
Table 2: Location of the stars according to Fig. 1. The results for the individual stars are listed in Table 3.
Table 3: The results for $\lambda$ Bootis stars taken from Paunzen et al. (2002) according to Fig. 1 and Table 2. We would only consider the stars of group (5) as good candidates for undetected spectroscopic binary systems, and no conclusion can be drawn for group (6).
