Abstract:
Position angles and separations resulting from 2406 speckle
interferometric observations of 547 binary stars are tabulated. 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 δm ≤ 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)/ρ in position angle, where ρ is
the separation in arcseconds.

Note (1): Coordinates from the Washington Double Star catalog
Note (2): The fit grades are subjective and are intended to provide only
a qualitative assessment of the measures
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 week and
fuzzy secondary image
Note (3):
B = Bar effects
D = Double secondary
E = Elongation in x and y
F = Elongation in x
G = Elongation in y
U = Uncertain results
W = Weak and fuzzy secondary
