cds-question@unistra.frmultiple-starsinterferometryWe present relative astrometric measurements of visual binaries made during the first semester of 2007, with the Pupil Interferometry Speckle camera and COronagraph (PISCO) at the 102-cm Zeiss telescope of Brera Astronomical Observatory, in Merate. Our sample contains orbital couples as well as binaries whose motion is still uncertain. We obtained 226 new measurements of 214 objects, with angular separations in the range 0.15-4.5arcsec, and an average accuracy of 0.013arcsec. The mean error on the position angles is. Most of the position angles could be determined without the usual 180{deg} ambiguity with the application of triple-correlation techniques and/or by inspection of the long integration files. We also present the new orbits we have computed for ADS 7871, 7982 and 8128, for which our measurements lead to large residuals and/or for which the revision is justified by the significant number of observations made since the publication of the previous orbit.2009MNRAS.395..907Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/395/907CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/367/1170 : PISCO speckle observations in 2004 (Scardia+, 2006)J/AN/330/55 : PISCO speckle observations in 2006 (Scardia+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/395/907https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/395/907http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/395/907https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/395/907https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/395/907http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/395/907GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/395/907/table1 (Measurements of binaries with PISCO and residuals with published orbits.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/395/907/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/395/907/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/395/907/table1?GETtext/xml+votable180.050000true3.349671726.98754640.0055555555555555566/283 349 409 455 486 502 640 742 823 900 941 1165 1182 1247 1267 1271 1292 1302 1309 1376 1381 1415 1434 1481 1506 1552 1627 1677 1686 1711 1870 1923 1939-1940 1976 1983 2036 2042 2171 2347 2395 2460 2465 2550 2817 2849 2856 2867 3030-3031 3076 3137 3139 3146 3284 3301 3308 3346 3393 3410 3650 3710 3713 4143 4161 4164 4184 4319 4434 4441 4493 4648 4670 4689 4695 4798 4847 4858 4942 5013 5015 5077 5091 5157 5298 5362 5377 5434 5455 5476 5540 5545 5689 5711 5762-5763 5785 5802 5995 6028 6126 6251 6278 6340 6367 6408 6432 6471 6529 6714 6804 6941 7117 7122 7139 7181 7194 7241 7252 7319 7371 7388 7465 7595 7845 7950 10378 10445 11011 11204 17888 18003 19823 20298 21815 21905 21937 21976 21987 22263 22837 22882 22964 22978 22989 22992 23005 23017 23373 23377 23423 23444 23450 23474 23492 23527 23539 23637 23639 23696 23702 23719 23735 23852 23869 23968-23969 24058 24076 24125 24148 24158 24214 24233 24235 24256 24281 24332 24404 24451 24467 24478 24480 24484 24557 24570 25577 26174 26211 26376 26420 26926 27010 27057 27295 27409 27439 27491 27496 27641 27822 27875 27968 28061 28186 28233 28352 28412 28556 28645https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/395/907?format=asciidefaultJ/MNRAS/395/907/table1Measurements of binaries with PISCO and residuals with published orbits.recnoRecord number assigned by the VizieR team.
