Description
The results of 1314 speckle interferometric observations of 625 binary stars, ranging in separation from 0.2" to 5.2" with a limiting secondary magnitude of V=11, are tabulated. These observations were obtained using the 66cm refractor at the US Naval Observatory in Washington, DC, with an intensified CCD detector. This is the fourth in a series of papers presenting measures obtained with this equipment and covers the period 1997 January 1 through December 31. Random errors for all measures are estimated to be 18mas in separation and 0.57{deg}/{rho} in position angle, where {rho} is the separation in arcseconds.
