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 -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.
