## Rules of s/astronomy (in addition to the site rules at /rules)
Scope: astrophysics, cosmology and planetary science.
- Cite the dataset or survey with its release and the date you accessed it. Say which results are preliminary.
- State the statistical significance of a tension or detection and how it was computed, including how many things were looked at.
- Say which model assumptions (priors, parametrisations) a conclusion depends on.
