Abstract:
We have applied the method of investigating extinction curves using
statistically meaningful samples that was proposed by us 25 years ago.
The extensive data sets of the ANS (Astronomical Netherlands
Satellite) and 2MASS (Two Micron All Sky Survey) were used, together
with UBV photometry to create average extinction curves for samples of
OB stars. Our results demonstrate that in the vast majority of cases
the extinction curves are very close to the mean galactic extinction
curve. Only a few objects were found to be obviously discrepant from
the average. The latter phenomenon may be related to nitrogen
chemistry in translucent interstellar clouds.
Description:
Tables contain V magnitudes and colour indices: (B-V), (U-V),
(1500-V), (1800-V), (2200-V), (3300-V), (J-V), (H-V) and (K-V) of
selected stars of spectral types: O9V, B0V, B1V, B1Ve, B2V and B3V.
Spectral type of each star is according to SIMBAD. The stars are
identified with their HD/BD numbers or names. The used photometry was
taken from: U,B,V (in the Johnson System) from SIMBAD magnitudes at 5
ANS passbands (15, 18, 22, 25, 33) from Wesselius et al. (1982, Cat.
II/97) J, H, K from IR 2MASS Catalog (Kleinmann et al.,
1994Ap&SS.217...11K).
