Abstract (from CDS):

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 66 cm 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 18 mas in separation and 0°.57/ρ in position angle, where ρ is the separation in arcseconds.
