However, until now, observational difficulties have prevented us from taking full advantage of these powerful Galactic archeological tools. CAPOS, the bulge Cluster APOgee Survey, addresses this key topic by observing a large number of BGCs, most of which have only been poorly studied previously. We aim to obtain accurate mean values for metallicity, [{alpha}/Fe], and radial velocity, as well as abundances for eleven other elements. Here we present final parameters for all 18 CAPOS BGCs. We use atmospheric parameters, abundances and velocities from ASPCAP in DR17. First, we carry out a stringent selection of cluster members, finding a total of 295 having spectral SNR>70. We reinforced the finding that stars with high [N/Fe] abundances show higher [Fe/H] than their lower [N/Fe] counterparts. Mg, Ca and global {alpha} abundances show similar trends, while Si is well-behaved. The [Fe/H] value of these 2nd population stars is corrected to derive the mean metallicity. Mean metallicities are determined to a precision of 0.05dex, [{alpha}/Fe] to 0.06dex, and radial velocity to 3.4km/s. No clusters show strong evidence for internal metallicity variations. Abundances for eleven other elements using only 1st population stars are calculated. Our values are generally in good agreement with the literature. We developed a new chemodynamical GC classification scheme, synthesizing recent studies. We also compile up-to-date metallicities. The BGC metallicity distribution is bimodal, with peaks near [Fe/H]=-0.45 and -1.1, with the metal-poor peak strongly dominant. The entire in situ sample, including Disk and BGCs, shows the same bimodality, while ex situ GCs are unimodal, with a peak around -1.6. Surprisingly, we find a negligible difference in the mean [Si/Fe] of in and ex situ GCs.2025A&A...703A.267Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/703/A267CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/284 : APOGEE-2 data from DR16 (Johnsson+, 2020)https://www.sdss.org/dr17/irspec : APOGEE Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/703/A267https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/703/A267http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/703/A267https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/703/A267https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/703/A267http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/703/A267GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/703/A267/capos-id (CAPOS member stars in 18 globular clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/703/A267/capos-id?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/703/A267/capos-id?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/703/A267/capos-id?GETtext/xml+votable180.050000true255.557535-26.222863890.0055555555555555566/28768-28769 28833 28835 28838 28867-28868 28876 28959 28966-28967 28972-28974 29184 29187 29195 29216 29218 42360-42361https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/703/A267?format=asciiInfrareddefaultJ/A+A/703/A267/capos-idCAPOS member stars in 18 globular clustersrecnoRecord number assigned by the VizieR team.
