J/A+A/458/113   BVRIc photometry towards inner Galactic Bulge  (Santiago+, 2006)

Multiband photometry towards the inner Galactic Bulge: extinction, atmospheric parameters and metallicities. Santiago B.X., Javiel S.C., Porto de Mello G.F. <Astron. Astrophys. 458, 113 (2006)> =2006A&A...458..113S
ADC_Keywords: Photometry, UBVRI ; Milky Way ; Extinction Keywords: Galaxy: abundances - Galaxy: Bulge - Galaxy: structure - Galaxy: stellar content - Galaxy: center - dust, extinction Abstract: We have obtained BVRI photometry for 21 stellar fields located in directions towards the central 3.5° of the Galaxy. Each field is 10x10 arcmin in size, and a total of ∼2x105 stars were measured. Description: 4 files containing photometric data on 4 directions located within the central 3.5° of the Galaxy, where extinction is lower than usual. Equatorial coordinates (J2000.0) and optical BVRI magnitudes obtained at Pico dos Dias, Laboratorio Nacional de Astrofisica, Brasil, are combined with near infra-red data from the 2 Micron All Sky Survey, providing a long spectral baseline for over 100.000 stars in these low-extinction windows. The file names indicate the galactic longitude and latitude of each region. File Summary:
