We thank Frank Fekel for obtaining additional spectra for us at KPNO and for re-measuring his earlier radial velocities. Many thanks also to Greg Henry for communicating his TSU-APT data prior to publication and to the referee, K. Stepie, for drawing our attention to the binary coalescence scenario. KGS is very grateful to the Austrian Fond zur Förderung der wissenschaftlichen Forschung for support under grants S7302-AST (Doppler imaging) and S7301-AST (APT) and also thanks K. Oláh and Konkoly Observatory for their hospitality during several visits. JB and ZsK acknowledge support by the Hungarian Research Grant OTKA T-019640 and F-019642. JB also thanks the ÖAD for a travel grant to Vienna. Finally, we all wish to thank NOAO/KPNO for devoting telescope time to long-term spectroscopy of active stars.
