cds-question@unistra.frgalaxiesinfrared-sourcessurveysThe FIRBACK (Far Infrared BACKground) survey is one of the deepest imaging surveys carried out at 170{mu}m with ISOPHOT onboard ISO, and is aimed at the study of the structure of the Cosmic Far Infrared Background. This paper provides the analysis of resolved sources. After a validated process of data reduction and calibration, we perform intensive simulations to optimize the source extraction, measure the confusion noise ({sigma}_c_=45mJy), and give the photometric and astrometric accuracies. 196 galaxies with flux S>3{sigma}_c_ are detected in the area of 3.89 square degrees. Counts of sources with flux S>4{sigma}_c_ present a steep slope of 3.3+/-0.6 on a differential ``logN-logS'' plot between 180 and 500mJy. As a consequence, the confusion level is high and will impact dramatically on future IR deep surveys. This strong evolution, compared with a slope of 2.5 from Euclidian geometry, is in line with models implying a strongly evolving Luminous Infrared Galaxy population. The resolved sources account for less than 10% of the Cosmic Infrared Background at 170{mu}m, which is expected to be resolved into sources in the 1 to 10mJy range.2001A&A...372..364Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/372/364CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/iso : ISO Observation Log (ISO Team, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/372/364https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/372/364http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/372/364https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/372/364https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/372/364http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/372/364GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/372/364/table7 (ISO FIRBACK Source Catalog for the FIRBACK South Marano Field (FSM))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/372/364/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/372/364/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/372/364/table7?GETtext/xml+votable180.050000true47.35417-54.867780.005555555555555556Cone search capability for table J/A+A/372/364/table8 (ISO FIRBACK Source Catalog for the FIRBACK North 1 Field (FN1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/372/364/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/372/364/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/372/364/table8?GETtext/xml+votable180.050000true241.4666754.112780.005555555555555556Cone search capability for table J/A+A/372/364/table9 (ISO FIRBACK Source Catalog for the FIRBACK North 2 Field (FN2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/372/364/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/372/364/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/372/364/table9?GETtext/xml+votable180.050000true249.387540.873890.005555555555555556Cone search capability for table J/A+A/372/364/table10 (Complementary catalog in FSM)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/372/364/table10?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/372/364/table10?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/372/364/table10?GETtext/xml+votable180.050000true48.525-55.270.005555555555555556Cone search capability for table J/A+A/372/364/table11 (Complementary catalog in FN1)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/372/364/table11?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/372/364/table11?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/372/364/table11?GETtext/xml+votable180.050000true242.9166754.290.005555555555555556Cone search capability for table J/A+A/372/364/table12 (Complementary catalog in FN2)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/372/364/table12?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/372/364/table12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/372/364/table12?GETtext/xml+votable180.050000true249.27541.402780.005555555555555556ISO5/2538 6/9634-9635 9640-9642 10147 10150 10156 33634-33635 33640-33641https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/372/364?format=asciiInfrareddefaultJ/A+A/372/364/table7ISO FIRBACK Source Catalog for the FIRBACK South Marano Field (FSM)recnoRecord number assigned by the VizieR team.
