Abstract:
The results of 1031 speckle-interferometric observations of double
stars, made with the 26 inch refractor of the U.S. Naval Observatory,
are presented. Each speckle-interferometric observation of a system
represents a combination of over two thousand short-exposure images.
These observations are averaged into 457 mean relative positions and
range in separation from 0.15" to 16.94", with a median separation of
3.03". The range in V-band magnitudes for the primary (secondary) of
observed targets is 3.1-12.9 (3.2-13.3).

Global notes:
Note (G1): Notes as follows:
C = confirming observation
1 = earlier 2006 data not published (Mason et al., 2007, Cat. J/AJ/134/1671)
due to larger than expected positional change
2 = earlier 2004 data not published (Mason et al. 2006, Cat. J/AJ/131/2687)
due to larger than expected positional change
3 = this pair was "rediscovered" and had its position corrected from
arcminute to arcsecond in the WDS.
4 = earlier 2005 data not published (Mason et al., 2006, Cat. J/AJ/132/2219)
due to larger than expected positional change
