VizieR Online Data Catalog: Orbits based on SOAR speckle interferometry. II. (Tokovinin, 2017)

We present new or updated orbits of 44 binary systems or subsystems. It is based on speckle interferometric measurements made at the 4.1m Southern Astrophysical Research (SOAR) telescope (Tokovinin et al. 2010, Cat. J/AJ/139/743; 2014, Cat. J/AJ/147/123; 2015, Cat. J/AJ/150/50; 2016, Cat. J/AJ/151/153; 2010PASP..122.1483T; Tokovinin 2012, Cat. J/AJ/144/56) combined with archival data collected in the Washington Double Star Catalog (WDS; Mason et al. 2001-2014, Cat. B/wds). It continues previous work on binary orbits resulting from the SOAR speckle program and follows the template of the Paper I (Tokovinin 2016, Cat. J/AJ/152/138), where the motivation is discussed. Briefly, the calculation of binary orbits is part of the astronomical infrastructure, and visual orbital elements are used in many areas. The state of the art is reflected in the Sixth Catalog of Visual Binary Orbits (VB6; Hartkopf et al. 2001AJ....122.3472H; http://www.usno.navy.mil/USNO/astrometry/optical-IR-prod/wds/orb6.html).
