Extended Source Catalog Criteria: Choices

Select an Extended Source Catalog based on:

• "extendedness" only.
  • Advantage: doesn't discriminate against galactic sources
  • Disadvantage: won't meet galaxy reliability criteria

• "extendedness" plus color criteria.
  • Advantage: meets galaxy reliability criteria and provides what many users want: a galaxy catalog
  • Disadvantage: possibly discriminates against galactic sources (but they could be retrieved from the database later)
