Speckle interferometry at USNO. II.

Listed in IVOA Registry (Virtual Observatory)

Position angles and separations resulting from 2406 speckle interferometric observations of 547 binary stars are tabulated.

Description

This is the second in a series of papers presenting measures obtained using the 66 cm refractor at the US Naval Observatory in Washington, DC, with an intensified CCD detector. Program stars range in separation from 0.2'' to 3.8'', with {delta}m {<=} 2.5 mag and a limiting magnitude of V = 10.0.

The observation epochs run from 1993 January through 1995 August. Random errors are estimated to be 14 mas in separation and (0.52 degrees)/{rho} in position angle, where {rho} is the separation in arcseconds.
