Note (1): Single-star internal errors are reported for those stars for which any
           Stroemgren index exceeds 2.5 times the appropriate mean uncertainty
           reported in Table II
Note (2): The error given to m195 magnitudes is twice the one derived by the
           CAPELLA software, see Viton et al (1991)
Note (3): a uncertain error bar
          b VWFC image elongated, both HD 204779 and 204763 may contribute
          c CORAVEL data indicate possibly variable velocity
          d CORAVEL data indicate variable velocity
          e UV detection in fact due to WT026bis (Fig. 3, V≃12.5) which
             preliminary spectroscopy and CCD photometry has shown is a sdO
             star probably in binary association with a cooler companion
          f SAO 227683 excluded
          g SAO 227683 included
          h photometric and spectroscopic variable, suspected EB
            (see Prevot et al., 1993)
