Description
The Lynds' Catalog of Bright Nebulae lists coordinates, dimensions, area, color, and a brightness index on a scale from 1 to 6 for each object. It originates from the NASA/ADC CD-ROM 'Selected Astronomical Catalogs Vol. 1' dated 09-July-1992, with corrections added by the CDS and a revision by NASA HEASARC in February 2001. The catalog includes cross-references to other major catalogs like NGC, IC, and Sharpless.
Use Cases
Classifying nebulae based on brightness index and color comparisons between blue and red plates.
Mapping the spatial distribution of bright nebulae using listed coordinates and dimensions.
Cross-referencing objects with other major catalogs like NGC, IC, and Sharpless for integrated studies.
Strengths
Includes a specific brightness index on a scale from 1 to 6 for each object.
Provides cross-references to multiple established catalogs (NGC, IC, Sharpless, Cederblad).
Has undergone revisions by authoritative sources like CDS and NASA HEASARC.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data originates from a 1992 source, though revised in 2001; observational methods may be dated.
Provenance
Source
NASA/ADC CD-ROM 'Selected Astronomical Catalogs Vol. 1', with revisions by CDS and NASA HEASARC.
Collection Method
Compiled from photographic plates, likely the blue and red Palomar plates.
