Description:
    Extinction values and distances have been computed from UBV, MK
    and beta data for more than 11000 O to F stars, including 7565
    O and B stars. For 1020 stars two independent distance moduli were
    derived using MK and beta absolute magnitudes. The mean values
    of their differences is less than 0.01mag.

Note (1): Remark to HD number as:
      0 = normal star
      1 = A component, 2 = B component, etc
      99 = combination of two consecutive HD numbers
Note (2): the first two bytes identify the catalogue
     BD = Bonner Durchmusterung
     CD = Cordoba Durchmusterung
     CP = Cape Photographic Durchmusterung
     .. = not in any Durchmusterung
Note (3): The code for luminosity class is defined as:
    10 = Ia ;    11 = Iab ; 12 = Ib ; 13 = I ;  15 = Ia+ ;  17 = Ib-II
    20 = II ;                                   25 = II-III
    30 = III ;                                  35 = III-IV
    40 = IV ;                                   45 = IV-V
    50 = V
    60 = no luminosity class known only for O stars (Mk type classified
         from slit spectra) or luminosity class V assumed for derivation
         of the "photometric Mk type", if no beta-value is known.
    70,71,72 apparently used for Wolf-Rayet, WC and WN stars
    88 = galactic cluster (temperature class is always 0)
    99 = δ Cep star (temperature class is always 990)
Note (4): The code for temperature class is C*100+subdivision, where
    C = 0 : O-type  (or Wolf-Rayet stars when luminosity class is 70,71 or 72)
    C = 1 : B-type
    C = 2 : A-type
    C = 3 : F-type
    C = 9 : only δ Cep star (associated to luminosity class is 99)
    Example: 115 means: B1.5
Note (5): The code for spectral peculiarities is defined as:
    06 = MK: or (MK)  07 = n      08 = e      09 = p
                      17 = (n)    18 = (e)    19 = (p)
    26 = MK::         27 = nn     28 = e!     29 = p!
    30 = f            31 = k      32 = ?      33 = var.
    example: 270908 means "nnpe"Note (6): the Numeration Code introduced by Mermilliod (1978) was
