In this paper we describe the construction of a
Compiled Catalogue (CC) of about 30 000 stars in a nearby region of star
formation including the Per OB2 association. The CC is a photometric and
astrometric survey with the center at
and radius of 10 degrees.
The CC is based on recently published astronomical catalogues, e.g.
Hipparcos and Tycho-2, and supplemented by relevant astrophysical
data from numerous data sources. The CC is complete down to
mag, in general, and to
mag in the one square degree field
centered around the IC 348 cluster. We describe the reduction procedures
allowing us to put the data onto one homogeneous system, i.e.,
the coordinates and proper motions on the Hipparcos system and the
photometry on the Johnson system. Typical accuracies of 1... 20 mas for coordinates, 1... 3 mas/yr for proper motions and 0.01... 0.05 mag for B, V magnitudes were achieved for the bright
CC stars (
mag). For ≈
7000 stars we also collected
parallaxes and spectral classes.
Down to the completeness limit of the CC, a
preliminary proper motion selection yielded more than 1000
probable members of Per OB2. The catalogue
is available in electronic form from the CDS at Strasbourg.
