Abstract:
The ESA Hipparcos satellite made measurements of over 12,000 double
stars and discovered 3406 new systems. In addition to these, 4706
entries in the Hipparcos Catalogue correspond to double star solutions
that did not provide the classical parameters of separation and
position angle (ρ, θ) but were the so-called problem stars,
flagged "G," "O," "V," or "X" (field H59 of the main catalog). An
additional subset of 6981 entries were treated as single objects but
classified by Hipparcos as "suspected nonsingle" (flag "S" in field
H61), thus yielding a total of 11,687 "problem stars." Of the many
ground-based techniques for the study of double stars, probably the
one with the greatest potential for exploration of these new and
problem Hipparcos binaries is speckle interferometry. Results are
presented from an inspection of 848 new and problem Hipparcos
binaries, using both archival and new speckle observations obtained
with the USNO and CHARA speckle cameras.

Global notes:
Note (G1): Type of information made available:
G: stars have acceleration terms applied to their astrometry,
which may indicate a close binary
O: solutions are those where a Keplerian orbital solution of the
photocenter was determined
S: suspected nonsingle with no satisfactory solution that fit the
previous categories
V: objects are "variability-induced movers", whose duplicity is
inferred via a photocentric motion due to the variability of
one of the components
X: solutions are those where a stochastic model is fitted to systems
with a nonzero physical scatter in excess of the measurement noise
