cds-question@unistra.frseyfert-galaxiesactive-galactic-nucleispectroscopyWe have completed an optical spectroscopic survey of the nuclear regions (r<=200pc) of a large sample of nearby galaxies. Although the main objectives of the survey are to search for low-luminosity active galactic nuclei and to quantify their luminosity function, the database can be used for a variety of other purposes. This paper presents measurements of the spectroscopic parameters for the 418 emission-line nuclei, along with a compilation of the global properties of all 486 galaxies in the survey. Stellar absorption generally poses a serious obstacle to obtaining accurate measurement of emission lines in nearby galactic nuclei. We describe a procedure for removing the starlight from the observed spectra in an efficient and objective manner. The main parameters of the emission lines (intensity ratios, fluxes, profile widths, and equivalent widths) are measured and tabulated, as are several stellar absorption-line and continuum indices useful for studying the stellar population. Using standard nebular diagnostics, we determine the probable ionization mechanisms of the emission-line objects. The resulting spectral classifications provide extensive information on the demographics of emission-line nuclei in the nearby regions of the universe. This new catalog contains over 200 objects showing spectroscopic evidence for recent star formation and an equally large number of active galactic nuclei, including 46 that show broad H{alpha} emission. These samples will serve as the basis of future studies of nuclear activity in nearby galaxies.1997ApJS..112..315Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/112/315CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/155 : 3rd Reference Cat. of Bright Galaxies (RC3) (de Vaucouleurs+ 1991)J/ApJS/98/477 : Optical spectral atlas of Seyfert nuclei (Ho+ 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/112/315https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/112/315http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/112/315https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/112/315https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/112/315http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/112/315GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/112/315/table7 (Stellar continuum magnitudes and colors)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/112/315/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/112/315/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/112/315/table7?GETtext/xml+votable180.050000true5.096559.2929720.0055555555555555565/6941 6/538 664 700 816 932 975 1701 1707 2121 2130 2142 2155 2214 2230 2251 2282 2311 2320 2324 2354 2362 2372 2374 2380 2383 2409 2504 2564 2622 2687 2709 2774 2777 3042 3078 3085 3389 3446 3506 3511 3558 4149 4188 4405 4439 4447 4471 4511 4891 4989 4990 5061 5067 5125 5142 5182 5183 5196 5200 5202 5241 5244 5342 5428 5429 5469 5482 5492 5504 5545 5572 5581 5587 5589 5596 5599 5610 5628 5629 5631 5634 5639 5715 5751 5793 5818 5966 5975 5976 5978 5982 5995 6003 6010 6012 6013 6034 6037 6087 6093 6098 6103 6448 6605 6619 6649 7030 7132 7214 7225 7241 7287 7355 7374 7385 7386 7424 7457 7498 7550 7602 7604 7606 7624 7642 7655 7659 7743 7878 7896 7941 7957 7986 7997 8010 8042 8067 8085 8106 8113 8169 8173 8193 8195 8196 8225 8256 8320 8359 8458 8506 8922 8944 9437 10402 10454 10475 10490 10518 10523 10628 10637 10650 10674 10723 10727 10755 10761 10781 10817 10841 10856 10878 10888 10892 10900 10905 10911 10912 10924 10925 10927 10930 10935 10941 10954 10977 10979 10980 10982 10986 10990 10991 11000 11006 11027 11127 11227 11246 11263 11372 11375 11389 11392 11394 11434 11435 11443 11446 11448 11457 11460 11566 11582 11639 11726 11738 11772 11791 11824 11961 12005 12018 12019 12025 12122 12619 13124 13336 13401 13489 13522 13672 15056 15592 15955 16098 16108 16120 17754 17755 17780 17855 17905 18011 18184 18209 18212 18214 18242 18269 18325 18379 18387 18398 18935 19576 19611 19614 19697 20000 20014 20225 20226 20270 22654 23075 23887 23921 25083 25647 25971 25972 26055 26065 26068 26072 26090 26091 26223 26234 26265 26271 26285 26303 26307 26309 26313 26316 26330 26331 26336 26338 26346 26351 26361 26362 26365 26377 26388 26472 26542 26803 27030 27079 27106 27255 27285 27426 27458 27504 27512 27514 27515 27518 27603 27604 27606 27653 27704 27712 27713 27714 27718 27719 27721 27728 27734 27735 27736 27738 27739 27741 27743 27757 27758 27773 27774 27814 27823 27828 27857 27860 27861 27862 27871 27901 27905 27907 27908 27913 27914 27917 27918 27926 27931 27936 27937 27938 27942 27944 27945 27947 27955 28015 28023 28033 28035 28036 28038 28039 28045 28046 28123 28141 28142 28167 28172 28173 28184 28191 28200 28208 28213 28221 28234 28254 28264 28267 28299 28304 28435 28463 28491 28495 28496 28498 28515 28516 28517 28521 28524 28529 28535 28538 28612 28631 28651 28653 31345 31880 31998 32426 32545 36785https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/112/315?format=asciiOpticaldefaultJ/ApJS/112/315/table7Stellar continuum magnitudes and colorsrecnoRecord number assigned by the VizieR team.
