cds-question@unistra.frinterstellar-mediummolecular-cloudsradio-astronomygalaxy-classification-systemsThe Five College Radio Astronomy Observatory (FCRAO) Outer Galaxy Survey (OGS) of ^12^CO(J=1-0) emission was carried out between 1994May and 1997September, using the FCRAO focal plane array QUARRY (Erickson et al. 1992, IEEE Trans. 40, 1), and initially described by Heyer et al. (1998ApJS..115..241H). The OGS covers the Galactic area 102.5<l<141.5, -3<b<54, and the velocity range -152km/s<vlsr<40km/s, at 45'' spatial resolution sampled every 50.22'', and 0.98km/s velocity resolution (1.39km/s for l<106) sampled every 0.81km/s. The typical sensitivity of the OGS at these resolutions is 0.6K (T*_R_ temperature scale). The catalog was generated in a two-phase object identification procedure. The first phase consists of grouping pixels into contiguous structures above a radiation temperature threshold of 0.8K; the second phase decomposes the first-phase objects by an enhanced version of the CLUMPFIND algorithm, using dynamic thresholding, and again with a threshold of 0.8K used for discrimination. Basic attributes of the clouds (coordinates, bounding boxes, integrated intensities, peak observed temperatures) are tabulated in the catalog. A two-dimensional elliptical Gaussian is fitted to the velocity- integrated map of each cloud; the major and minor axis sizes and major axis position angles thus derived are included in the catalog. To the spatially integrated emission line of each cloud, a Gaussian profile is fitted to measure the global linewidth. Model Gaussian clouds, truncated at 0.8K, are examined to determine the effects of biases on measured quantities, induced by truncation. Coupled with detailed analysis of the catalogued clouds, statistical corrections for the effects of truncation on measured sizes, linewidths, and integrated intensities are derived and applied, along with corrections for the effects of finite resolution on the measured attributes. The catalogued emission accounts for 76.4% of the total emission in the Outer Galaxy Survey. The deficit is shown to arise mainly from low-intensity emission on the periphery of larger objects, rather than from a large number of small and/or low-intensity features.2003ApJS..144...47Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/144/47CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/cgps : Canadian Galactic Plane Survey (CGPS) (CADC, 2001-)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/144/47https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/144/47http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/144/47https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/144/47https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/144/47http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/144/47GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/144/47/table3 (Properties of objects decomposed from the Five College Radio Astronomy Observatory 12CO(J=1-0) Survey of the Outer Galaxy)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/144/47/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/144/47/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/144/47/table3?GETtext/xml+votable180.050000true341.8079862.315740.0055555555555555564/191 204 205 206 225 227 228 232 233 891 893 894 895 977 980 5/757 758 759 761 762 763 813 815 828 829 830 864 905 906 907 916 920 921 922 936 937 938 3570 3571 3905 3907 3913 3916 3917 3924 3925 3926 6/2943 3005 3006 3007 3023 3027 3042 3043 3179 3182 3183 3229 3231 3257 3259 3324 3325 3326 3464 3466 3488 3597 3599 3617 3619 3668 3670 3672 3673 3674 3692 3693 3694 3696 3756 3757 3758 3760 3761 3762 3764 3768 3776 3777 3778 14203 14205 14206 14207 14234 14235 14237 14238 14239 14245 14247 14253 14254 14255 14277 14278 14279 15651 15657 15660 15661 15672 15673 15708 15709 15712 15713 15714 15716 15717https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/144/47?format=asciiOpticalRadiodefaultJ/ApJS/144/47/table3Properties of objects decomposed from the Five College Radio Astronomy Observatory 12CO(J=1-0) Survey of the Outer GalaxyFlagFlag value (17)meta.codeintrecnoRecord number assigned by the VizieR team.
