Discussion Overview
The discussion revolves around the creation of a comprehensive list comparing various star catalogs, specifically FK5, HD, BD, NGC, IC, and proper names like the Eagle Nebula. The focus is on proper motion and cross-identifications among these catalogs.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant seeks a comprehensive comparison between FK5, HD, BD, NGC, IC, and proper names, emphasizing the importance of proper motion.
- Another participant notes the complexity of the question due to the unique numbering systems of different catalogs and mentions that no single source provides all cross-identifications.
- A participant suggests using the Simbad database to find cross-identifications for specific objects.
- One participant expresses a desire for a database that equates SAO numbers with constellation and alpha-beta-gamma designations.
- Several links to databases are provided, including those that connect FK5, SAO, HD, and Bayer/Flamsteed, as well as the Yale Bright Star catalogue, which contains cross-identifications.
Areas of Agreement / Disagreement
Participants generally agree on the complexity of the task and the lack of a single comprehensive source for all catalog comparisons. Multiple competing views and resources are presented without a consensus on the best approach.
Contextual Notes
The discussion highlights limitations in existing resources, such as the absence of a unified database for all star catalog cross-identifications and the dependence on specific catalogs for proper motion data.
