J/AJ/134/1671       Speckle interferometry at USNO. XIII          (Mason+, 2007)

Speckle interferometry at the US naval observatory. XIII. Mason B.D., Hartkopf W.I., Wycoff G.L., Wieder G. <Astron. J., 134, 1671-1678 (2007)> =2007AJ....134.1671M
ADC_Keywords: Stars, double and multiple Keywords: binaries: general - binaries: visual - techniques: interferometric Abstract: The results of 1424 speckle interferometric observations of double stars, made with the 26 inch (66cm) refractor of the US Naval Observatory, are presented. Each speckle interferometric observation of a system represents a combination of over 2000 short-exposure images. These observations are averaged into 1053 mean relative positions and range in separation from 0.36" to 61.92", with a median separation of 10.31". This is the 13th in a series of papers presenting measurements obtained with this system and covers the period 2006 January 12-December 29. Included in these data are nine older measurements whose positions were previously deemed possibly aberrant but are no longer classified this way following a confirming observation. This paper also includes the first data obtained using a new "secondary" camera, designed and built at USNO. File Summary:

Note (1): Object notes as follows: C = Confirming Observation P = Given the proper motion and time since the last observation, this pair is identified as a common proper motion binary 1 = Also known as BEM 15. 2 = Earlier 2004 data not published (Mason et al., 2006, Cat. J/AJ/132/2219) due to larger than expected positional change 3 = Earlier 2005 data not published (Mason et al. 2006, Cat. J/AJ/131/2687) due to larger than expected positional change 4 = Also see Table 1 5 = Hyperbolic orbit to this pair given in Hopmann (1967MiWie..13...49H)

Note (1): Flag as follows: C = System used in calibration * = System used in characterizing errors 1 = This measure was inconsistent with previous measures, so not included in Mason et al. (2006, Cat. J/AJ/131/2687). However, available data are deemed insufficient for a new orbital calculation at this time 2 = This system was expected to show significant motion over the calendar year, so multiple observations have been obtained

Note (1): Notes as follows: 1 = The DM cross reference given in Couteau (1966JO.....49..221C) does not match the coordinates in the paper, but the pair is not found at either location 2 = Hipparcos "suspected nonsingle" (Perryman et al. 1997, I/239, field H61), possibly due to input catalog listing, but no indication of duplicity here 3 = Three measures from 1874 to 1894 (Wilson & Seabroke 1875, MmRAS, 42, 59; 1877, MmRAS, 43, 105; Glasenapp 1895, Mesures Micrometriques d'Etoiles Doubles Faites a St. Petersbourg et a Domkino, Vol. 3 (St. Petersburg: Impr. Acad. Imperiale Sci.)) and nothing since. Since 1894 the AB pair has been measured 67 times with no accompanying measure of the wide pair
