Speckle interferometry at SOAR in 2016 and 2017 J/AJ/155/235 ivo://CDS.VizieR/J/AJ/155/235 doi:10.26093/cds/vizier.51550235 CDS Tokovinin A. Mason B.D. Hartkopf W.I. Mendez R.A.

We describe briefly recent changes in the instrument and observing method and quantify the accuracy of the pixel scale and position angle calibration. Comments are given on 44 pairs resolved here for the first time. The orbital motion of the newly resolved subsystem BU 83 Aa,Ab roughly agrees with its 36-year astrometric orbit proposed by J. Dommanget. Most Tycho binaries examined here turned out to be spurious. 2018AJ....155..235T https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/155/235 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to B/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014) I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007) I/337 : Gaia DR1 (Gaia Collaboration, 2016) J/AJ/139/743 : Speckle interferometry in 2008-09 (Tokovinin+, 2010) J/AJ/143/42 : Speckle interferometry with SOAR in 2010 & 2011 J/AJ/144/56 : Speckle interferometry at SOAR in 2012 (Tokovinin+, 2012) J/AJ/147/123 : Speckle interferometry with SOAR in 2012-2013 (Tokovinin+, 2014) J/AJ/150/50 : Speckle interferometry at SOAR in 2014 (Tokovinin+, 2015) J/AJ/151/153 : Speckle interferometry at SOAR in 2015 (Tokovinin+, 2016) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/155/235 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/155/235 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/155/235 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/155/235 https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/155/235 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/155/235 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/AJ/155/235/table3 (Measurements of double stars at SOAR) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/155/235/table3? https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/155/235/table3? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/155/235/table3?
