7106 VII/106 Open Cluster Interstellar Matter Database D T Leisawitz NASA Ref. Publ. 1202 ??? ??? 1988 1988NASAR1202....1L Clusters, open Interstellar gas Interstellar dust, Interstellar clouds 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.
