cds-question@unistra.frmetallicityradial-velocityphotometryWe have recalibrated a method for the estimation of stellar metal abundance, parameterized as [Fe/H], based on medium-resolution (1-2{AA}) optical spectra (the majority of which cover the wavelength range 3700-4500{AA}). The equivalent width of the Ca II K line (3933{AA}) as a function of [Fe/H] and broadband B-V color, as predicted from spectrum synthesis and model atmosphere calculations, is compared with observations of 551 stars with high-resolution abundances available from the literature (a sevenfold increase in the number of calibration stars that were previously available). A second method, based on the Fourier autocorrelation function technique first described by Ratnatunga & Freeman (1989, Cat. <V/65>), is used to provide an independent estimate of [Fe/H], as calibrated by comparison with 405 standard-star abundances.1999AJ....117..981Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/117/981CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/107/1577 : Halo red giants reddening (Anthony-Twarog+, 1994)J/AJ/115/168 : Kinematics of red giant and RR Lyrae stars (Chiba+ 1998)V/65 : Spectroscopically Selected Halo K Giants (Ratnatunga+ 1989)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/117/981https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/117/981http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/117/981https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/117/981https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/117/981http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/117/981GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/117/981/stars (Observed and derived parameters for program stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/117/981/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/117/981/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/117/981/stars?GETtext/xml+votable180.050000true215.43859030.78310390.0055555555555555566/89 94 146 154 208 373 382 798 2736 2921 3712 4129 4184 4376 4383 4423 4429 4506 4694 4714 4760 4905 5166 5195 5258 5413 5458 5555 5621 5868 5929 6036 6051 6058 6159 6186 6256 6348 6792 7019 7211 7251 7424 7613 7710 7767 8205 8210 8216 8235 8250 8255 8274 8296 8314 8354 8371 8377 8385 8866 8999 9004 9065 9121 9162 9224 9505 9992 10359 10458 10476 10943 11065 11197 11412 11920 12295 12321 12355 12358-12359 12381 12397 12424 12451 12621 12645 12650 12704 12771 12844 13020 13025 13075 14385 14534 14693 14743 15176 16409 16582 16587 16759 16776 16795 16808 16821 16871 16912 16935 17099 17124 17136 17138 17171 17234 17245 17343 17369 17412 17477 17509 17538 17545 17564 17578 17617 18193 18290 18425 18553 18561 18637 18639 18707 18719 18735 18839 18936 18945 18990 19022 19064 19076 19083 19100 19244 19342 19378 19603 19973 20390 20562 20646 20680 21209 21269 21299 21389 21485 21809 21866 21920 22071 22130 22162 22186 22193 22205 22302 22334 22401 22420 22436 22451 22558 22743 22748 22771 22882 22998 23011 23013 23015 23070 23096 23190 23192 23360 23428 23567 23607 23695 23818 23887 23978 24678 24683 24733 24752 24834 24877 24942 25051 25074 25182 25200 25331 25385 25397 25444 25554 25567 25569 25573 25591 25595 25607 25753 25767 25790 25834 25838 25846 25854 25891 25906 25948 25963 25966 26025 26030-26031 26044 26109 26187 26239 26260 26284 26289 26292 26305 26344 26347 26366 26380 26457 26528 26534 26546 26552 26576 26728 26812 26852 26873 26989 27040 27062 27073 27075 27091 27128 27162-27163 27224 27239 27255 27323 27330 27380 27394 27456 27503 27592 27661 27681 27763 27767 27775 27777 27796 27857 27920 27948 27975 27991 28038 28044 28154 28181 28257-28258 28336 28338 28342 28347 28396 28421 28459 28664 29490 29548 29593 29640 29703 29769 29915 30051 30131 30166-30167 30179 30296 30359 30464 30489 30528 30553 30577 30831 30891 30929 30939 30965 30974 31094 31100 31132 31136 31145 31306 31347 31354 31366 31368 31393 31395 31397 31416 31472 31501 31503 31585 31650 31677 31748 31757 31826 32034 32302 32343 32352 32468 32593 32743 32889 33058 33131 33470 33515 33566 33642 33831 33929 34096 34171 34600 34684 35532 35647 35702 35750 35768 35913 35948 36084 36135 36221 36365 36700 36705 36737 36745 36755 36813 36888 36919 37040 37125 37185 37232 37282 38216 38255 38506 38868 39647 39692 39709 40214 40222 40333 40337 40351 40567 40624 40716 40750 40831 40908 40916 40925 40931 40944 40950 41259 41460 41721 41831 42076 42331 42496 43062 43310 43360 43445 43534 43546 43613 43769 43786 43788 43838 43945 43962 44121 44208 44281 44542 44575 44771 44816 44940 45694 45790 45796-45797 45808 45818 45825 46023 46506 46626 46661 46796 47040 47092 47125 47147 47168 47344 47347 47441 47459 47556 47596 47698 47876 48188 48281 48501 48525 48555 48636 48719 48731 48736 48798 48824 48862 48946 49009 49027 49063 49078https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/117/981?format=asciiOpticaldefaultJ/AJ/117/981/starsObserved and derived parameters for program starsStarStar namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
