\footnotemark{~Information for star HD~294297
comes from the SIMBAD database. Identifiers and photometry of Dolan 24 
in $\lambda$~Ori were taken from Dolan \&
Mathieu (\cite{dm99}). \teff~for HD~294297 was retrieved from Cunha et~al.
(\cite{cun98}), while that of Dolan 24 was estimated from the $R-I$ color.
Radial velocities were measured from our spectra.}
