$^{\rm M}$, $^{\rm D}$ and  $^{\rm 2M}$ correspond to Massey (\cite{Massey02}), DENIS and 2MASS  
catalogues respectively. \\
$^{\rm W}$ $V$ magnitudes and spectral types from Wilcots (\cite{Wilcots94b}).\\
 $^{\rm H}$, Str\"omgren $y$ (F547) magnitudes from HM99. For the stars 27, 28 and 32,
 spatially resolved into double or triple stars by the 
HST, the given magnitudes correspond to the sum of their components and are not 
affected by    the  brightness  excess  due to  dust scattering. \\
