J/AJ/140/480        Speckle interferometry at USNO. XV.      (Mason+, 2010)

Speckle interferometry at the U.S. Naval Observatory. XV. Mason B.D., Hartkopf W.I., Wycoff G.L. <Astron. J., 140, 480-482 (2010)> =2010AJ....140..480M
ADC_Keywords: Stars, double and multiple ; Interferometry Keywords: binaries: general - binaries: visual Abstract: Results of 2433 intensified CCD observations of double stars, made with the 26 inch refractor of the U.S. Naval Observatory, are presented. Each observation of a system represents a combination of over 2000 short-exposure images. These observations are averaged into 1013 mean relative positions and range in separation from 0.96" to 58.05", with a mean separation of 13.50". This paper is the 15th in the series of papers and covers the period 2008 January 3 through 2008 December 21. File Summary:

Note (1): Notes as follows: C = Confirming Observation P = Based on proper motion of the primary and the time since the last observation, this pair appears to be physical. 1 = Big change in position since the discovery in Baillaud (1943, Ann. Obs. Besancon New Ser., 3, 33 ). 2 = The 2007 measure, being of lower quality and very different from the discovery measure of Aitken (1901LicOB...1...66A), was not included in Mason et al. (2008, Cat. J/AJ/136/2223). With this confirmation the earlier measure is presented as well. 3 = Partial elements in Hopmann (1960MiWie..10..227H). 4 = The 2007 measure was very different from the discovery measure of Soulie (1983A&AS...54..281S) and was not included in Mason et al. (2008, Cat. J/AJ/136/2223). With this confirmation the earlier measure is presented as well. Note (2): Name "SHJ 151" converted into "SHJ 161", see the "History" section below.
