The goal of this study is to analyse the properties of galaxies showing Wolf-Rayet features in their optical spectrum using spectra from the Sloan Digital Sky Survey Release 6. With this unprecedentedly large sample we aim to constrain the properties of the Wolf-Rayet phase and its impact on the surrounding interstellar medium. We carried out very careful continuum subtraction on all galaxies with equivalent widths of H{beta}>2{AA} in emission and identify Wolf-Rayet features using a mixture of automatic and visual classification. We combined this with spectroscopic and photometric information from the SDSS and derive metal abundances using a number of methods.2008A&A...485..657Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/485/657CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/136/35 : WR galaxies and HII regions catalog (Schaerer+ 1999)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/485/657https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/485/657http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/485/657https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/485/657https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/485/657http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/485/657GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/485/657/catalog (Positional and physical parameters of Wolf-Rayet galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/657/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/657/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/657/catalog?GETtext/xml+votable180.050000true145.891251.11652220.0055555555555555566/1702 4110 4181 4191 4276 4298 4314 4328 4445 4456-4457 4462 4470 4496 4503 4511 4518 4536 4650 4706 4709 4730 4758 4840 4849 4882 4891 4897 4925 4956 4961 5018 5026 5028 5057 5082 5100 5123 5128 5133 5142 5148 5162 5173 5181 5186 5190 5193 5195-5196 5202 5215 5223 5225 5241 5244 5249 5263 5295 5332 5342 5359 5394 5396 5400 5414 5440 5468 5482 5487 5498 5504 5531 5545 5554 5556 5581 5589-5590 5604 5607 5623-5624 5629 5635 5647-5648 5661 5665 5671 5698 5715 5751 5757 5771 5775 5799 5874 5894 5902 5912 5933 5959 5971 5975 5993 5995 6011 6016 6034 6042 6063 6075 6094 6104 6108 6450 6463 6470 6575 6600 6604-6605 6609 6619 7181 7207-7208 7235 7259 7270 7272 7281 7283 7298 7303 7308 7328 7340-7341 7379 7381 7523-7524 7527 8284 8328 8331 8359 8364 8378 8416 8509-8510 8520 8526 8645 8657 8663 8674 8677-8678 8713 8721 8724 8736 8914 8940-8941 8946 8952 8984 9084 9086 9099 9106 9123 9133 9135 9161 9216 9231 9253 9280 9319 9352 9355 9402 9418 9441 9444 9611-9612 9799 9824 9852-9853 9855 9880 9915 9943 9952 9997 10085 10104 10106 10144-10145 10202 10219 10296 10348 10366 10382 10393 10421 10427 10433 10439-10441 10444 10452 10454 10459 10461 10472 10475 10491 10540 10561 10565 10583 10619 10635 10705 10708 10737 10755 10761 10765 10769 10771 10773-10774 10782 10789 10818 10833 10841 10862 10867 10888 10892 10905 10911 10914 10936-10937 10955 10970 10977 10991 11006 11009 11027 11048 11084 11104 11115-11116 11171 11186 11196 11201 11223 11234 11238-11239 11247 11258 11269 11290 11308 11312 11326 11376 11380 11388 11403 11433-11434 11475 11480 11596 11800 11816 12383 17240 17320 17492 17520 17570 17747 17750 17754 17761 17763-17764 17773 17997 18002 18013 18019 18024 18063 18086 18098 18295 18302 18367 18523 18603 18618 18624 18801 18845 18949-18950 19045 19323 19406 19754 19756 19763 19842 20003 21877 22399 23183 23194 23204 23207 23212 25597 25846 25849 25906 25938 25946-25947 25952 25955 25968 25974 25989 26002 26011 26014 26080 26108 26110 26142 26159 26161 26167 26178 26205 26214 26234 26248 26260 26265 26289 26301-26302 26323 26326 26331 26338 26341-26342 26362 26377 26392 26400 26411 26460 26467 26472 26488 26512 26555 26580 26585 26601 26606 26967 26970-26971 26974 26979 26984 27022 27031 27034 27049 27062 27088 27222-27223 27226 27243 27259-27260 27319-27320 27330 27334 27343 27347 27356 27384 27390 27392 27446 27458 27463 27466 27485 27494 27516 27518 27548 27555 27562 27575 27581 27652-27653 27656-27657 27668 27677 27691 27697 27728 27732 27763 27772 27796 27811 27855 27860-27861 27884 27906 27948 28126 28147 28152 28154 28167 28173 28180 28203 28218 28253 28373 28397 28402 28408 28410 28476 28496 28515 28520-28521 28528 28535 28561 28585 28587 28604 28617 28633 28639 28661 28663 31146 31293 31316 31477 31656 31694-31695 31731 32408 32482 32680 32682 36727 36767 36784-36785 49013 49094 49101 49124https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/485/657?format=asciiOpticaldefaultJ/A+A/485/657/catalogPositional and physical parameters of Wolf-Rayet galaxiesrecnoRecord number assigned by the VizieR team.
