cds-question@unistra.frdwarf-starslate-type-starsmetallicityvisible-astronomyWe present a catalogue of 551214 main-sequence stars in the local (d<2kpc) Galactic thick disk and halo, based on a search of stars with large proper motions (>40.0mas/yr) in the Gaia Early Data Release 3. We derive photometric metallicity calibrated from the colour-luminosity-metallicity distribution of 20047 stars with spectroscopic metallicities, collected from various spectroscopic surveys, including SDSS SEGUE/APOGEE, GALAH DR3, and LAMOST DR6. We combine these results to construct an empirical colour- magnitude-metallicity grid, which can be used to estimate photometric metallicities for low-mass metal-poor stars of K and M subtypes from their absolute G magnitude and colour values. We find that low-mass, high-velocity stars in our catalogue share similar kinematics as reported in recent studies of more luminous Galactic halo stars. The pseudo-kinematic analysis of our sample recovers the main local halo structures, including the Gaia-Enceladus Stream and the Helmi stream; aside from these the local halo stars appear to show a remarkably smooth distribution in velocity space. Since the future Gaia data release will provide radial velocity measurements for only a small number of our sample, our catalogue provides targets of high interest for the future spectroscopic observation programs.2022MNRAS.510.4308Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/510/4308CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/350 : Gaia Early Data Release 3 (Gaia Collaboration 2020)III/284 : APOGEE-2 data from DR16 (Johnsson+, 2020)J/MNRAS/506/150 : The GALAH+ Survey DR3 (Buder+, 2021)J/AJ/159/30 : High proper-motion M-type stars spectroscopic obs.J/AJ/137/4377 : List of SEGUE plate pairs (Yanny+, 2009)http://argonaut.skymaps.info : Interactive 3D dust maphttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/510/4308https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/510/4308http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/510/4308https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/510/4308https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/510/4308http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/510/4308GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/510/4308/table6 (Catalogue of candidates in the Galactic thick disk and halo in Gaia EDR3)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/510/4308/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/510/4308/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/510/4308/table6?GETtext/xml+votable180.050000true268.10092811.06667220.0055555555555555560/2 4 6 8 11 1/5 7 12-14 23 29-31 36-38 40 42-43 2/2 5-6 8-9 11 13-17 19 24-25 27 62-63 80 82-83 88 90-91 113-115 159 164 167 3/0 2-5 12-13 15 18-19 28 30-31 40-42 50-51 72 74-75 104-105 107 240 242-244 246-247 324-325 327 337 339-341 343-345 348 350 356 358-359 449-451 625-629 631-633 635 660-662 664 666-667 4/4-5 7 24-25 27-30 57-59 64-66 69-71 117-119 172-174 192 194-198 293-294 424-426 964 966-967 980-981 983 1304 1306-1307 1344-1346 1352-1353 1355 1368-1370 1384-1386 1388-1390 1396 1398-1399 1404-1405 1407 1429-1431 1792-1793 1795 2496-2497 2499 2521-2523 2537-2539 2652 2654-2655 2661-2662 5/24-26 104-106 124-126 224 226-227 268 270-272 274-275 464-466 701-703 772-774 797-799 1168-1169 1171 1180 1182-1183 1708-1710 3860-3861 3863 3928-3929 3931 5220-5221 5223 5388-5390 5416-5418 5485-5487 5548-5550 5564-5565 5567 5589-5591 5624 5626-5627 5713-5715 7176-7178 9992 9994-9995 10080-10082 10144-10146 10612-10614 10641-10643 10652 10654-10655 6/108-110 428 430-431 508 510-511 901-903 1076-1077 1079 1093-1095 1868-1870 2800 2802-2803 3101-3103 3184-3186 4680-4682 4725-4727 6844 6846-6847 15448-15449 15451 15720 15722-15723 20889-20891 21564 21566-21567 21676-21677 21679 21936-21937 21939 22204 22206-22207 22264-22265 22267 22352 22354-22355 22500-22501 22503 22848 22850-22851 28716-28717 28719 39972-39973 39975 40332 40334-40335 40588-40590 42461-42463 42560 42562-42563 42612-42614https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/510/4308?format=asciiOpticaldefaultJ/MNRAS/510/4308/table6Catalogue of candidates in the Galactic thick disk and halo in Gaia EDR3_RA.icrsRight ascension (ICRS) at Epoch=J2000, proper motions taken into accountdegpos.eq.ranullableindexed_DE.icrsDeclination (ICRS) at Epoch=J2000, proper motions taken into accountdegpos.eq.decnullableindexedrecnoRecord number assigned by the VizieR team.
