cds-question@unistra.frquasarsinfrared-sourcesinfrared-photometryvisible-astronomyphotometryEight luminous quasars with -30<M_B_<-27 at z=1.4-3.7 have been observed in the mid- and far-infrared using ISO. All the quasars have been detected in the mid-infrared bands of ISOCAM, while no far-infrared detections have been made with ISOPHOT. SEDs (Spectral Energy Distributions) from the UV to far-infrared have been obtained while supplementing ISO observations with photometry in the optical and near-infrared made from the ground within 17 months. The SEDs are compared with the MED (Mean spectral Energy Distributions) of low-redshift quasars with -27<M_B_<-22. It is shown that our far-infrared observations were limited by confusion noise due to crowded sources.2001A&A...365..409Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/365/409CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/238/1171 : Optical/IR obs. of Radio Galaxies and QSOs (Dunlop+, 1989)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/365/409https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/365/409http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/365/409https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/365/409https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/365/409http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/365/409GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapISOOpticalInfrareddefaultJ/A+A/365/409/table3List of ISO flux if quasarsrecnoRecord number assigned by the VizieR team.
