Description
The SMC&BridgeClustersCatalog is the Small Magellanic Cloud and Inter-Magellanic Cloud 'Bridge' portion of the 'Revised and Extended Catalog of Magellanic System Clusters, Associations, and Emission Nebulae'. It contains 1188 extended objects identified from the ESO/SERC R and J Sky Survey Atlases, including 544 star clusters, 343 associations, and 291 emission nebulae. This database table was created by NASA's HEASARC in February 1998 based on a version obtained from the CDS catalog J/ApJS/101/41.
Use Cases
Classifying stellar objects based on the provided object classification (cluster, association, nebula).
Analyzing spatial distributions and hierarchical relations based on provided positions and cluster pair information.
Cross-referencing astronomical catalogs using the included cross-identifications with previous catalogs.
Studying object morphology using the provided homogeneous sizes and position angles.
Strengths
Contains 1188 identified extended objects with specific counts: 544 star clusters, 343 associations, and 291 emission nebulae.
Provides accurate positions, classification, homogeneous sizes, and position angles for each object.
Includes 284 newly identified objects and cross-identifications with previous catalogs.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Only includes objects detectable as non-stellar on ESO/SERC Schmidt films, typically larger than 15 arcseconds, which may introduce a selection bias.
Row count is unknown, which may limit suitability assessment.
Provenance
