cds-question@unistra.frmolecular-cloudsradio-astronomypolarimetryWe use extensive 350{mu}m polarimetry and continuum maps obtained with the Hertz polarimeter and SHARC II (Submillimeter High Angular Resolution Camera II) along with HCN and HCO+ spectroscopic data to trace the orientation of the magnetic field in the Orion A star-forming region. Using the polarimetry data, we find that the direction of the projection of the magnetic field in the plane of the sky relative to the orientation of the integral-shaped filament varies considerably as one moves from north to south. By combining the polarimetry and spectroscopic data, we were able to measure a set of average values for the inclination angle of the magnetic field relative to the line of sight. We also present polarimetry data for the OMC-4 region located some 13' south of OMC-1.2004ApJ...604..717Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/604/717CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/125/1537 : QUIRC Chandra sources in OMC 2/3 (Tsujimoto+, 2003)J/ApJ/566/974 : CHANDRA obs. of YSOs in OMC-2 and OMC-3 (Tsujimoto+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/604/717https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/604/717http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/604/717https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/604/717https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/604/717http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/604/717GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/604/717/table2 (OMC-1, 350 micron Results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/604/717/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/604/717/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/604/717/table2?GETtext/xml+votable180.050000true83.794149-5.44924240.005555555555555556Cone search capability for table J/ApJ/604/717/table3 (OMC-2, 350 micron Results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/604/717/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/604/717/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/604/717/table3?GETtext/xml+votable180.050000true83.8474931-5.21999880.005555555555555556Cone search capability for table J/ApJ/604/717/table4 (OMC-3 and IRAS 05327-0457, 350 micron Results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/604/717/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/604/717/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/604/717/table4?GETtext/xml+votable180.050000true83.8534029-5.1050260.005555555555555556Cone search capability for table J/ApJ/604/717/table5 (OMC-4, 350 micron Results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/604/717/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/604/717/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/604/717/table5?GETtext/xml+votable180.050000true83.7690817-5.60878350.0055555555555555566/21438 21439 22805https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/604/717?format=asciiRadiodefaultJ/ApJ/604/717/table2OMC-1, 350 micron ResultsrecnoRecord number assigned by the VizieR team.
