cds-question@unistra.frinfrared-sourcesinfrared-photometryWe present a study of ISOGAL sources in the "intermediate" galactic bulge (|l|<2{deg}, |b|~1{deg}-4{deg}), observed by ISOCAM at 7 and 15{mu}m. In combination with near-infrared (I, J, Ks) data of DENIS survey, complemented by 2MASS data, we discuss the nature of the ISOGAL sources, their luminosities, the interstellar extinction and the mass-loss rates. A large fraction of the 1464 detected sources at 15{mu}m are AGB stars above the RGB tip, a number of them show an excess in ([7]-[15])_0_ and (Ks-[15])_0_ colours, characteristic of mass-loss. The latter, especially (Ks-[15])_0_, provide estimates of the mass-loss rates and show their distribution in the range 10^-8^ to 10^-5^M_{sun}_/yr.2003A&A...403..141Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/403/141CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/denis : The DENIS database (Epchtein+, 1999)B/2mass : The 2MASS database (IPAC/UMass, 2000)II/243 : The ISOGAL Point Source Catalogue - IGPSC (Omont+ 2003)V/107 : MSX5C Infrared Point Source Catalog (Egan+ 1999)J/A+A/362/199 : YSOs in the l=+45 ISOGAL field (Felli+, 2000)J/A+A/392/971 : Catalogue of bright YSO candidates in ISOGAL (Felli+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/403/141https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/403/141http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/403/141https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/403/141https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/403/141http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/403/141GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/403/141/table2a (Catalogue of ISOGAL-DENIS sources from nine intermediate bulge fields with their 2MASS (<B/2mass>) & MSX (<V/107>) counterparts.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/403/141/table2a?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/403/141/table2a?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/403/141/table2a?GETtext/xml+votable180.050000true264.39648-29.766630.005555555555555556Cone search capability for table J/A+A/403/141/table2b (Sub-sample of ISOGAL-DENIS sources from table2a.dat with Av, mass-loss rate & luminosity values.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/403/141/table2b?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/403/141/table2b?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/403/141/table2b?GETtext/xml+votable180.050000true264.42438-29.751750.005555555555555556ISO6/28778 28818-28819 28821 28823-28825 28828 28848-28849 28852-28853 28864 288727.947616174868663e-21 2.689546822829005e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/403/141?format=asciiInfrareddefaultJ/A+A/403/141/table1Log of ISOCAM, DENIS and 2MASS observations in the intermediate bulge fields.2MASSDateDate of 2MASS JHKs Obs.time.epochnullablerecnoRecord number assigned by the VizieR team.
