cds-question@unistra.frastrometryproper-motionsA catalogue of accurate positions and proper motions for 41,721 objects is provided. Objects are within areas of special astronomical interest, containing extragalactic radio sources, mostly from ICRF (see Cat. I/251), and pre-main-sequence (PMS) stars in Southern star-forming regions (Chamaeleon, Lupus and Upper Scorpius-Ophiuchus). Positions and proper motions were derived by combining current epoch positions, obtained with the Valinhos CCD meridian circle (VMC, see 1999A&AS..134..173V), with first epoch catalogues, AC2000 (I/247) and USNO-A2.0 (I/252) mainly, as well as positions from plate measurements performed with the MAMA measuring machine (Guibert J., Charvin P. & Stoclet P., 1983, in Proceedings of the 78th Colloquium of the IAU), in Paris. On average, objects with V<=14.0 have positional precisions better than 50mas in both coordinates, and 100mas near the detection limit of the VMC (V~16,0). For proper motions, average precisions are better than 4mas/year, whatever the magnitude, when delta>=-17{deg}. To the south of this declination, a magnitude dependence is verified due to a particular feature of the USNO-A2.0's epochs, providing figures of 3mas/year when V<=12.0, where the participation of AC2000 is noted, and reaching 17mas/year at the detection limit. The catalogue data is grouped by area, following the same order and identification as given in table 2 of the paper; within each area, objects are sorted by right ascension. The respective record numbers for the beginning of each area are provided in a separate table.2001A&A...375..308Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/375/308CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/247 : The AC2000 Catalogue (Urban+ 1997)I/251 : VLBI International Celestial Reference Frame (ICRF) (Ma+, 1997)I/252 : The USNO-A2.0 Catalogue (Monet+ 1998)I/259 : The Tycho-2 Catalogue (Hog+ 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/375/308https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/375/308http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/375/308https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/375/308https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/375/308http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/375/308GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/375/308/vmcc (Valinhos meridian circle catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/375/308/vmcc?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/375/308/vmcc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/375/308/vmcc?GETtext/xml+votable180.050000true0.0242958310.975030560.0055555555555555565/4667-4668 4743 4752 4890-4891 4908 9598 9681 10327 10332 10394 10405 10853-10854 10857 11070 11149 11153-11154 6/15 35-38 40-42 2059-2060 2062 2080-2082 4565-4567 4569-4572 4581-4583 4585 4588 4592 4747-4750 4768-4770 5146 5157-5159 5161-5164 5168 5248 5423 5427-5430 5432-5434 5507-5510 5512-5514 8285 8449-8452 8456 8598 8601-8604 8613-8615 8617-8620 8624 8767 8808-8810 8830-8831 8847 8851-8854 8856-8858 8867-8870 8872-8874 8909 8911 8913-8916 8920 8955 8960 10311 10315-10318 10320-10322 10337 16904 16906 17005-17007 17018 17053-17055 17069-17071 17073-17078 17080-17082 17089-17094 17096-17098 17791 17875-17878 17880-17881 18358-18359 18362-18366 18379 18400-18402 18433 18435-18438 18663 18667 18680 18967 19012 19016 19421 19423 19519 19550 19555 19558 19569-19572 19576 19599 19603-19606 19608-19610 19613-19614 19619-19622 19624-19626 19629-19631 19636 19640 19649-19652 19656 19719 19723-19726 19728-19730 19744-19745 19829-19831 19835-19838 19911 19920-19922 19969 19971-19972 20013-20015 20024 20097-20100 20104 22519 22523-22526 23888-23889 24582 24585-24588 24608 25249-25252 25256 25741-25743 25745-25747 25752 25761-25764 26271 26287 26291-26294 26296-26298 26307-26308 26310 26312-26314 27652-27653 28477-28479 28557-28559 28561-28564 28568-28569 28580 29222 29225-29228 29312 31645-31647 31661-31663 31665-31668 31672 31681-31684 31688 34103 34108-34109 34119 34123-34126 34144-34146 34867-34870 34872-34874 36062-36063 36077-36079 36081-36084 36088 36381-36383 36397-36398 36401-36404 36408 36417-36420 36424 36957-36959 36980 37121-37123 37128 37917-37919 37937 37939-37940 37954-37955 37960 38261-38263 38265 38267-38268 38383 38723 38729 38746-38747 38757-38759 38761-38764 38768 38805-38807 38809 38812 38848 38909-38911 40055 40059-40062 40135 40140-40141 40144-40146 40203 40206 40224-40226 40273 40275-40276 41133-41135 41307 41332 41476 41535 41580 41582 41629 41664-41666 42591 42607 42611-42614 42616-42618 42691-42694 42696-42697 42760 42762 42965-42967 42969-42972 42981-42983 42985-42988 42992 43253-43255 43257-43260 43327 43370 43407 43411 43420 43427 43433 43440 43456 43589-43591 43600 44245-44247 44249-44252 44271 44309-44311 44313 44315-44316 44329-44331 44352 44416 44575 44595 44601 44611 44620 44661-44663 44665 44668 44810-44811 44832 45775 45795-45798 45800-45802 45909 45911 46015 46043-46044 46046 46055-46056 46058-46062 46064-46066 46246-46247 46249-46252 46361-46363 46373-46375 46377 46379-46380 46384 46592 46757-46759 46761-46764 46768 46847 46941-46943 46957 46959 46961-46966 46968-46970 46991 46995-46996 46998 47000-47002 47011-47014 47016-47018 47231 47374-47375 47379-47382 47384-47386 47394-47398 47400-47402 47445 47447 47978-47979 48021-48023 48025-48030 48039 48048-48050 48064-48066 48128 48211-48214 48217 48623 48627 48630 48632-48634 48963-48966 48968-48970https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/375/308?format=asciiOpticaldefaultJ/A+A/375/308/vmccValinhos meridian circle catalogueEpRAR.A. epochyrtime.epochdoublerecnoRecord number assigned by the VizieR team.
