Figure 1: A comparison of the synthetic Strömgren-Crawford , Maitzen ( left panels) and the Geneva 7 color system ( right panels) with the observations for the group of  Bootis stars (full circles). The open circles are the binary models, whereas the grey shaded triangles are the single-star models used to construct them. Vega is marked with an asterisk, the two synthetic "standard''  Bootis stars are open triangles. The standard lines are from the literature.
