\caption{\label{Sp.data}Spectroscopic data. Column from left to
right: star number, Tycho (or Hipparcos) identification,
$V$~magnitude, $B-V$~colour, our spectral types and those from
literature (if avaiable), $E(B-V)$, $(B-V)_0$ and distance moduli. Colour
excesses and distance moduli have been computed using Lang's (1992) tables.
Colon indicates uncertainties in the intrinsic colours and/or absolute
magnitudes. The "negative'' reddening shown by star~\#28 could trace
an undetected binary.}
