Description:
This catalog is a compilation of the characteristics of 128 open clusters
and the interstellar medium associated with them. It is distributed as
the "OCISM Database" which is the set of data files, processing and analysis
software written in FORTRAN, and the supporting documentation. As provided
by the author, the data are in a multi-record format which is best accessed
with the author's software.
The clusters in this database have been relatively well-studied, have
declinations greater than minus 20 deg., are between 1 and 5 kpc distant,
and are younger than 100 million years old. Characteristics compiled for
these clusters include cluster identification, spatial coordinates, radial
velocities (of stellar clusters, H II regions, and molecular clouds), proper
motions, distance, angular diameter, linear diameter, age, mass (based on
stellar and atomic gas, ionized gas, molecular clouds, and dust
determinations), visual extinction, and reddening.
