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.
