Discussion Overview
The discussion revolves around the availability of Cartesian coordinates for galaxies, specifically within the local group. Participants are exploring resources and databases that provide these coordinates without the need for conversion from polar coordinates.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant inquires about existing lists of Cartesian coordinates for galaxies, particularly the local group.
- Another participant shares links to databases that contain stellar information, including coordinates and distances.
- A participant suggests the Tully database as a potentially useful resource for galaxy data.
- There is a question regarding the availability of Tully's database with specific software, indicating uncertainty about access.
- A participant provides additional links to Tully's collection and mentions the Nearby Galaxies Catalogue, while expressing difficulty in finding the larger Tully database in a downloadable format.
- Concerns are raised about the completeness and official release status of Tully's data, suggesting it may not be fully available yet.
Areas of Agreement / Disagreement
Participants appear to agree on the usefulness of the Tully database and the Nearby Galaxies Catalogue, but there is uncertainty regarding the availability and completeness of Tully's larger dataset.
Contextual Notes
Limitations include the potential incompleteness of Tully's data and the reliance on personal communication for access to certain datasets.
