Description:
Data on 728 stellar systems of multiplicity 3 to 7 are given. All
systems are physical and, with little exception, hierarchical. They
are represented as several "elementary binaries". For each binary the
orbital period and separation are given, as well as component
magnitudes, spectral types and estimated masses. Orbital elements are
also given when available. The present (1999) version of the catalogue
is updated as compared to the original 1997 publication, with some
changes in the format.
