cds-question@unistra.frmilky-way-galaxymolecular-cloudsThe Galactic center is the closest region in which we can study star formation under extreme physical conditions like those in high-redshift galaxies. We measure the temperature of the dense gas in the Central Molecular Zone (CMZ) and examine what drives it. We have mapped the inner 300pc of the CMZ in the temperature-sensitive J=3-2 para-formaldehyde (p-H_2_CO) transitions. We use the 3_2,1_-2_2,0_/3_0,3_-2_0,2_ line ratio to determine the gas temperature in n~10^4^-10^5^cm^-3^ gas. We produce temperature maps and cubes with 30" and 1km/s resolution and publish all data in FITS form; they can be recovered from digital object identifier doi:10.7910/DVN/27601.2016A&A...586A..50Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/586/A50CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/586/A50https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/586/A50http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/586/A50https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/586/A50https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/586/A50http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/586/A50GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/586/A50/fitted (Fitted line parameters Chi2 constraints)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/586/A50/fitted?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/586/A50/fitted?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/586/A50/fitted?GETtext/xml+votable180.050000true267.3485279044-27.598100091710.005555555555555556Cone search capability for table J/A+A/586/A50/temp (PPV H2CO temperature)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/586/A50/temp?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/586/A50/temp?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/586/A50/temp?GETtext/xml+votable180.050000true266.3605981-29.47144140.005555555555555556Cone search capability for table J/A+A/586/A50/list (list of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/586/A50/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/586/A50/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/586/A50/list?GETtext/xml+votable180.050000true266.8039383-28.5052160.0055555555555555566/28825 28827 28830-28831https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/586/A50?format=asciidefaultJ/A+A/586/A50/fittedFitted line parameters Chi2 constraintsGLONGalactic longitudedegpos.galactic.lonrecnoRecord number assigned by the VizieR team.
