cds-question@unistra.frdwarf-starsmetallicityvisible-astronomybroad-band-photometryWe present a revised metallicity distribution of dwarfs in the solar neighbourhood. This distribution is centered on solar metallicity. We show that previous metallicity distributions, selected on the basis of spectral type, are biased against stars with solar metallicity or higher. A selection of G-dwarf stars is inherently biased against metal-rich stars and is not representative of the solar neighbourhood metallicity distribution. Using a sample selected on colour, we obtain a distribution where approximately half the stars in the solar neighbourhood have metallicities higher than [Fe/H]=0. The percentage of mid-metal-poor stars ([Fe/H}<-0.5) is approximately 4 per cent, in agreement with the present estimates of the thick disc.2001MNRAS.325.1365Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/325/1365CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/325/1365https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/325/1365http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/325/1365https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/325/1365https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/325/1365http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/325/1365GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/325/1365/table3 (The list of 348 stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/325/1365/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/325/1365/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/325/1365/table3?GETtext/xml+votable180.050000true306.934344-30.8678460.0055555555555555566/60 100 137 309 377 742 819 1098 1341 1556 1875 2051 2167 2491 2622 2652 2697 3102 3118 3313 3372 3509 3639 3780 3979 4241 4278 4316 4591 4766 4854 4942 5009 5074 5154 5304 5413 5434 5488 5522 5670 5726 5836 5929 6217 6226 6273 6287 6308 6385 6409 6523 6662 6766 6926 6941 6953 7390 7763 8094 8109 8156 8224 8357 8466 8476 8746 8843 8995 9125 9476 9492 9662 9679 9801 9843 9873 10004 10375 10518 10598 10812 10899 10914 11126 11150 11165 11314 11405 11412 11633 11713 11834 12228 12388 12592 12846 12890 12983 13025 13036 13487 13547 13568 13763 13778 13791 14180 14278 14290 14342 14419 14502 14539 15030 15174 15221 15373 15861 15962 16069 16220 16393 16412 16518 16689 17171 17219 17266 17314 17425 17576 17607 17731 17944 18115 18139 18614 18641 18821 19109 19219 19327 19912 20127 20145 20328 20402 20593 20640 20701 21060 21177 21185 21197 21477 21484 21726 21838 21953 22708 23096 23140 23177 23190 23230 23369 23583 23661 23675 23774 23960 24016 24028 24036 24151 24160 24212 24558 24713 24729 24831 24924 25102 25407 25766 25880 25906 25966 26183 26429 26521 26652 26676 26761 26906 27374 27462 28122 28605 28664 28696 28987 29084 29255 29756 30015 30576 30665 30759 30878 30965 31029 31130 31132 31393 31399 31425 31433 31478 31768 32067 32211 32520 32561 32645 32757 32848 32930 33224 33456 33552 33717 33813 33818 33849 33854 33998 34442 34446 34508 34581 34817 34905 34947 35064 35079 35753 35802 36288 36365 36664 36693 36697 36762 37408 37479 37595 37780 38070 38238 38765 38788 38807 38932 38950 39034 39256 39284 39676 39693 40007 40078 40242 40488 40679 40692 40716 40784 40892 40932 40968 41163 41272 41460 41463 41612 41687 41721 41752 41941 42022 42115 42248 42700 42760 42845 42887 43065 43074 43258 43318 43756 43804 43989 44262 44557 44669 44792 44879 44891 45107 45265 45334 45386 45485 45535 45668-45669 45902 45941 45992 46076 46113 46247 46320 46640 46681 46734 46785 46982 47107 47589 47598 47740 47824 47949 48283 48291 48334 48652 48705 48768 49060https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/325/1365?format=asciiOpticaldefaultJ/MNRAS/325/1365/table3The list of 348 starsrecnoRecord number assigned by the VizieR team.
