Distribution and studies of the infrared stellar population in the Galaxy. V - Other clear regions around the Galactic centre
A number of stars with K less than or equal to +9.0 in three clearregions located at latitudes of approximately -3.5, -4.0, and -4.5,respectively, in the general direction of the Galactic center arestudied. An exponential disk model is used to separate these regionsinto disk and bulge cumulative counts functions (CCF). It is found that,for the case of Baade's window (BW) (Ruelas-Mayorga and Teague, 1992),the disk is dominant at bright magnitudes, whereas the bulge dominatesat the faint end of the CCF. The slope of the bulge CCF is steeper thanthat for the disk in all three cases confirming the result obtained forBW. The two color JHK diagram and the K vs J-K diagram for the threeregions reveal that the stellar population in these areas is similar tothat studied in BW.
| 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.
