cds-question@unistra.frseyfert-galaxiesspectroscopyWe analyse in detail the rich emission line spectrum of Mark 110 to determine the physical conditions in the nucleus of this object, a peculiar NLS1 without any detectable Fe II emission associated with the broad line region and with a {lambda}5007/H{beta} line ratio unusually large for a NLS1. We use 24 spectra obtained with the Marcario Low Resolution Spectrograph attached at the prime focus of the 9.2m Hobby-Eberly telescope at the McDonald observatory. We fitted the spectrum by identifying all the emission lines (about 220) detected in the wavelength range 4200-6900{AA} (at rest).2007A&A...475..487Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/475/487CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/475/487https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/475/487http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/475/487https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/475/487https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/475/487http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/475/487GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/475/487/tablea1Lines observed in the stronger narrow line systemrecnoRecord number assigned by the VizieR team.
