Walraven photometry of nearby southern OB associations
Homogeneous Walraven (VBLUW) photometry is presented for 5260 stars inthe regions of five nearby southern OB associations: Scorpio Centaurus(Sco OB2), Orion OB1, Canis Major OB1, Monoceros OB1, and Scutum OB2.Derived V and (B - V) in the Johnson system are included.
| IRAS point sources in the Ophiuchus molecular cloud complex - Optical identification
An attempt was made to optically identify 1433 IRAS point sources in a170 sq deg area of the Ophiuchus molecular cloud complex extending about45 pc from rho Oph to the north. Among 652 sources having fluxes of highor middle quality at 12 or 25-micron wavelengths, 577 are identifiedwith stars, four with galaxies, while 71 have no optical candidates to17 or 20 mag at I or R bands. With respect to the sources only detectedat 60 and/or 100 microns, 33 are associated with galaxies and theremainder may be infrared cirrus. On the basis of the detailed study onthe near-infrared Schmidt plates to 17 mag in a 5 x 5 deg area centeredon rho Oph, statistical properties of IRAS point sources are discussedwith emphasis on the correlation with the molecular clouds, making thisstudy useful for future studies of the global star formation in thecloud complex at near infrared or other wavelengths.
