cds-question@unistra.frmagnetic-fieldsinterstellar-mediumpulsarsWe have re-examined the published rotation measures (RMs) of extragalactic point sources and pulsars with |b|<3{deg} to study the magnetic field in the fourth Galactic quadrant. We reduced the influence of structure in electron density as much as possible by excluding objects for which H{alpha}-data indicate large fluctuations in n_e_ somewhere along the line of sight. We also excluded objects for which the RM may have been significantly "corrupted" by an intervening supernova remnant. We modelled RM(l), the longitude dependence of RM of the unaffected extragalactic sources and pulsars. We assumed several geometries for the large-scale field. All but one of those are based on logarithmic spiral arms (with various pitch angles and widths), while one has circular symmetry. We also made different assumptions about the large-scale n_e_-distribution.2010A&A...513A..65Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/513/A65CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/216 : H-alpha emission regions in Southern Milky Way (Rodgers+ 1960)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/513/A65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/513/A65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/513/A65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/513/A65https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/513/A65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/513/A65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/513/A65/extragal (Rotation measures from extragalactic sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/513/A65/extragal?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/513/A65/extragal?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/513/A65/extragal?GETtext/xml+votable180.050000true123.6949-35.85030.005555555555555556Cone search capability for table J/A+A/513/A65/psr (Rotation measures from pulsars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/513/A65/psr?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/513/A65/psr?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/513/A65/psr?GETtext/xml+votable180.050000true127.8847-44.09690.0055555555555555565/9429 9431 9822 9846 10419 10455 10595 6/28803 28807-28808 28812-28814 28816 37244 37332 37339 37341 37360-37361 37365-37366 37374-37375 37701 37714 37721 37735 37745-37746 37748-37749 37751 37757-37758 37830 37840-37842 37844 37848-37849 37852 37854 37873-37876 37878 37884 37892 37894-37895 37898 37900-37901 37903-37906 37910 37912 37914 37921 37923-37924 37927 37929-37931 37946 38017-38018 38020 38025 38027 38040 38048 38050 38058 38060 38400 38402 38406 38568 39235 39243 39249 39251 39269 39275 39277 39279-39281 39294 39375-39376 39378 39389 41470 41583 41594-41595 41597 41630-41631 41653-41654 41656-41657 41659-41660 41662 41665 41669 41672 41674 41682-41685 41689 41696-41698 41701 41704 41712 41757-41759 41765 41767 41770 41774 41777-41779 41781 41783 41796 41799-41801 41804-41806 41809-41813 41817-41819 41824 41840-41841 41856 41859 42147 42155 42158-42159 42171 42173 42206 42208-42209 42214 42217 42220-42221 42224 42226-42229 42231 42233 42366-42367 42371 42378 42384 42386 42391 42394 42396 42401 42433 42435 42438-42439 42450-42451 42456-42457 42459 42466 42481 42487 42496-42497 42502-42504 42506-42507 42513 42515 42560 43012 43014-43015 43017 43020 43022 43024 43042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/513/A65?format=asciiRadiodefaultJ/A+A/513/A65/extragalRotation measures from extragalactic sourcesrecnoRecord number assigned by the VizieR team.
