VizieR Online Data Catalog: Speckle interferometry at USNO. IX. (Mason+, 2004)
Abstract
The results of 3056 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 a thousand short-exposure images. These observations are averaged into 1675 mean relative positions and range in separation from 0.19" to 45.21", with a median separation of 2.99". This is the ninth in a series of papers presenting measures obtained with this system and covers the period 2002 January 1 through 2002 December 29. Included in these data are 28 older measures whose positions were previously deemed possibly aberrant but are no longer classified this way following a confirming observation. Nine of these systems have new orbital elements, which are presented here as well.
