Abstract:
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°/ρ in position angle, where ρ is the separation in
arcseconds.

Note (3): the Qualities are flagged as follows:
G: good fit with most of the points lying on the x and y parabolas
F: fair fit with at least three points lying on the parabolas
P: poor fit with points scattered about the parabolas
V: very poor fit with large scatter about the parabolas and a weak
and fuzzy secondary image
