cds-question@unistra.frsurveysinterstellar-mediummilky-way-galaxyradio-astronomyThe SEDIGISM (Structure, Excitation and Dynamics of the Inner Galactic Interstellar Medium) survey used the APEX telescope to map 84deg^2^ of the Galactic plane between l=-60{deg} and +31{deg} in several molecular transitions, including ^13^CO(2-1) and C^18^O(2-1), thus probing the moderately dense (~10^3^cm^-3^) component of the interstellar medium. With an angular resolution of 30arcsec and a typical 1{sigma} sensitivity of 0.8-1.0K at 0.25km/s velocity resolution, it gives access to a wide range of structures, from individual star-forming clumps to giant molecular clouds and complexes. The coverage includes a good fraction of the first and fourth Galactic quadrants, allowing us to constrain the large-scale distribution of cold molecular gas in the inner Galaxy. In this paper, we provide an updated overview of the full survey and the data reduction procedures used. We also assess the quality of these data and describe the data products that are being made publicly available as part of this First Data Release (DR1). We present integrated maps and position-velocity maps of the molecular gas and use these to investigate the correlation between the molecular gas and the large-scale structural features of the Milky Way such as the spiral arms, Galactic bar and Galactic Centre. We find that approximately 60 per cent of the molecular gas is associated with the spiral arms and these appear as strong intensity peaks in the derived Galactocentric distribution. We also find strong peaks in intensity at specific longitudes that correspond to the Galactic Centre and well-known star-forming complexes, revealing that the ^13^CO emission is concentrated in a small number of complexes rather than evenly distributed along spiral arms.2021MNRAS.500.3064Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/500/3064CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/601/A124 : Clouds in SEDIGISM science demonstration fieldhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/500/3064https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/500/3064http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/500/3064https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/500/3064https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/500/3064http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/500/3064GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/500/3064/tablea1 (Spectra observed towards the reference positions: measured rms and spectral lines detected)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/500/3064/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/500/3064/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/500/3064/tablea1?GETtext/xml+votable180.050000true187.0434-62.50050.0055555555555555565/7203 7206 7228 10420 10442 10444 10556 10595 6/28808-28809 28828 28830-28831 28852 28874-28875 28878 28896-28897 28900-28901 28918-28919 28925 29090-29091 29096-29097 29100-29101 29103 29112 29114-29115 29118-29119 29460-29461 29504-29505 30259 30262 30268 41598-41599 41653-41655 41657-41660 41662 41671 41675-41678 41684-41685 41688 41696-41698 41759 41766-41767 41772-41773 41780-41781 41801-41806 41810-41811 41813-41817 42158-42159 42169-42174 42207 42211 42214-42217 42228-42229 42378-42379 42390-42393 42396-42397 42400 42434-42435 42438-42441 42444-42445 42450-42451 42454 42456-42457 42460-42461 42496-42498 42500-42501 43013-43015 43020 43024https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/500/3064?format=asciiRadiodefaultJ/MNRAS/500/3064/tablea1Spectra observed towards the reference positions: measured rms and spectral lines detectedrecnoRecord number assigned by the VizieR team.
