Description:
We investigate the spatial distribution, the space velocities and
age distribution of the pre-main sequence (PMS) stars belonging to
Ophiuchus, Lupus and Chamaeleon star-forming regions (SFRs), and of
the young early-type star members of the Scorpius-Centaurus (Sco-Cen)
OB association. These young stellar associations extend over the
galactic longitude range from 280 to 360 degrees, and are at a
distance interval of around 100 and 200pc.
We present a compilation of PMS and early-type stars members of the
investigated SFRs and OB associations. For these lists of stars we
give the data used for the study of kinematic properties: positions,
adopted distances, proper motions and radial velocities (whenever
available), and the basic stellar data, used for the construction
of Hertzsprung-Russel diagrams. All data have been taken from the
literature. We also present the derived XYZ positions on the Galactic
system, UVW components of the space velocities, visual extinction,
and bolometric luminosity.

Global notes:
Note (G1): Proper motion in galactic longitude is multiplied by the
cosine of the galactic latitude
Note (G2): Effective temperature was obtained using the relationship
between SpType and Teff given by de Jager & Nieuwenhuijzen
(1987A&A...177..217D 1987A&A...177..217D)
Note (G3): Superficial gravity was derived from SpType and luminosity class
as given by Table VII of Straizys & Kuriliene (1981Ap&SS..80..353S 1981Ap&SS..80..353S)
Note (G4): These quantities were obtained by interpolation of values in
tables 1, 2, 3 or 6 of Bessel et al. (1998A&A...333..231B 1998A&A...333..231B)
Note (G5): These quantities were extracted or derived from Hipparcos Catalogue
or references therein (ESA, 1997, Cat. I/239)
