\caption{A comparison of the detection capability of the $\Delta a$ 
and Geneva $\Delta (V1 - G)$, as well as $Z$
indices for the objects with available Geneva 7-color photometry. No objects
of the CP1 and $\lambda$ Bootis group are within 
the range of valid $Z$ values (defined for stars hotter than A0).
The results are shown graphically in Fig. \ref{deltav1g}.}
