cds-question@unistra.frmultiple-starsinterferometryWe present relative astrometric measurements of visual binaries made during the second semester of 2006, with the speckle camera PISCO at the 102cm Zeiss telescope of Brera Astronomical Observatory, in Merate. Our sample contains orbital couples as well as binaries whose motion is still uncertain. We obtained 175 new measurements of 169 objects, with angular separations in the range 0.1"-4.2", and an average accuracy of 0.01". The mean error on the position angles is 0.6{deg}. 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 11479, 11584 and 16538, for which our measurements lead to large residuals and/or for which the revision was justified by the significant number of observations made since the last orbit computation.2009AN....330...55Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/330/55CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2011)J/MNRAS/367/1170 : PISCO speckle observations in 2004 (Scardia+, 2006)http://ad.usno.navy.mil/wds/obr6.html :https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/330/55https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/330/55http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/330/55https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/330/55https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/330/55http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/330/55GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/330/55/table1 (Measurements of visual binaries between July and December 2006)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/330/55/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/330/55/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/330/55/table1?GETtext/xml+votable180.050000true22.080376442.78222670.0055555555555555566/2816 9233 9294 9327 9500 9525 9591 10090 10097 10189 11377 11620 11740 12303 12325 12404 12408 12473 12668-12669 12774 12798 12833 12864 12938 12955 13096 13100 13204 13219 13292 13361 13631 13654 13665 13690 13721 13742 13752 13821 13888 14019 14058 14142 14213 14230 14256 14281 14316 14346 14354 14393 14396 14439-14440 14444 14459 14499 14512 14522 14549 14553 14585 14598 14617 14619 14665 14679 14702 14722 14760 14777 14786 14822 14839 14908 15010 15023 15093 15096 15102 15133 15141 15161 15214 15232 15246 15303 15323 15411 15463 15566 15600 15607 15631 15663 15675 15680 15686 15801 15865 16074 16087 16090 16092 16104 16128 16296 18973 19189 19360 19374 19442 19636 20097 20143 20402 20406 25940 30121 30349 30363 30374 30385 30438 30447 30525 30558-30559 30638 30642-30643 30717 31061 31073 31090 31204 31565 31570 31747 31763 31790 31884 31948 31967 32001 32004-32005 32024 32058 32084 32088 32100 32116 32144 32196 32200 32225 32336 32338 32375 32582 32593 32597 32743 32765https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/330/55?format=asciiOpticaldefaultJ/AN/330/55/table1Measurements of visual binaries between July and December 2006recnoRecord number assigned by the VizieR team.
