Comparisons
Comparing to other scopes is tricky, e.g.,
- Who’s the audience?
- What’s the purpose?
- How do you normalize paper or citation counts ?
- aperture area? (meaningless across wavelengths)
- program dollars? (space vs. ground!)
- photons?
- pointings!
HST has 15x the citation impact of a 4-m
ground-based telescope, but costs 100x as much.
