cds-question@unistra.frgalaxiesinfrared-sourcesinterstellar-mediumh-ii-regionsThe ISOPHOT experiment onboard the ISO satellite generated a complete view of the Small Magellanic Cloud (SMC) at 170{mu}m with 1.5arcmin resolution. The map is analysed using an automated photometry program enabling accurate photometric characterization of the far infrared (FIR) emitting regions. In this paper, the sources detected at 170{mu}m are compared with those obtainable from the IRAS satellite data. For this purpose, the 12{mu}m, 25{mu}m, 60{mu}m, and 100{mu}m IRAS high resolution (HiRes) maps of the SMC are re-examined using the same method. In contrast to former studies, this provides an all-band ISO/IRAS source catalog which is no longer based on eyeball classification, but relies on an algorithm which is capable of automated, repeatable photometry, even for irregular sources. In the mid infrared IRAS bands numerous bright FIR emitting regions in the SMC are detected and classified: 73 sources are found at 12{mu}m, 135 at 25{mu}m (most of them with F{nu}<1.0Jy). All three FIR bands at 170{mu}m, 100{mu}m, and 60{mu}m reproduce the overall morphological structure of the SMC similarly well, in contrast to the 12{mu}m and 25{mu}m maps which only contain a limited number of extended sources and do not trace the main body of the SMC. 243 sources are detected in the ISO 170{mu}m map, 155 of them with F{nu}>=2.0Jy. Comparable numbers are found for the two FIR IRAS maps at 60{mu}m (384) and 100{mu}m (338) with fluxes up to 450Jy. 70 of the 243 170{mu}m sources are assigned a general SED type (cold , warm , i.e., <30K, >30K) for the first time. A comparison with earlier IRAS results suggests that many source flux densities in those studies have been under- or overestimated because of non-standardized fitting methods. Many sources with flux densities up to 40Jy listed in former catalogs cannot be identified in our data.2003A&A...401..873Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/401/873CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/270 : Catalog of Positions of IR Stellar Sources (CPIRSS) (Hindsley+ 1994)I/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)II/156 : IRAS Faint Source Catalog, |b| > 10, Version 2.0 (Moshir+ 1989)VI/101 : ISO Observation Log (ISO Team, 2001)II/181 : IR sources in Magellanic Clouds (Schwering+ 1990)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/401/873https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/401/873http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/401/873https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/401/873https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/401/873http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/401/873GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/401/873/tablea (The IRAS 12{mu}m source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/401/873/tablea?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/401/873/tablea?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/401/873/tablea?GETtext/xml+votable180.050000true8.8125-73.510830.005555555555555556Cone search capability for table J/A+A/401/873/tableb (The IRAS 25{mu}m source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/401/873/tableb?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/401/873/tableb?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/401/873/tableb?GETtext/xml+votable180.050000true6.42083-73.457220.005555555555555556Cone search capability for table J/A+A/401/873/tablec (The IRAS 60{mu}m source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/401/873/tablec?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/401/873/tablec?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/401/873/tablec?GETtext/xml+votable180.050000true7.0375-72.981110.005555555555555556Cone search capability for table J/A+A/401/873/tabled (The IRAS 100{mu}m source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/401/873/tabled?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/401/873/tabled?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/401/873/tabled?GETtext/xml+votable180.050000true6.225-73.039720.005555555555555556Cone search capability for table J/A+A/401/873/tablee (The ISO 170{mu}m source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/401/873/tablee?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/401/873/tablee?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/401/873/tablee?GETtext/xml+votable180.050000true10.41667-73.037780.005555555555555556ISO5/8323 8326 8329 6/33286 33297-33299 33313 33315 33325 33328 33330 33336-333371.1684975007979438e-21 1.6553710307751707e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/401/873?format=asciiInfrareddefaultJ/A+A/401/873/tableaThe IRAS 12{mu}m source catalogN100? cross identification number in `slave' catalog (100{mu}m IRAS) (G1)meta.idcharrecnoRecord number assigned by the VizieR team.
