Notes in articles aren't OR?!?
Time and time again I keep seeing data added to astronomy articles referenced to notes that are formulas, and I'm thinking there must be a policy that says that this an exception to the Original Research policy. Can someone explain, or point me to the exception policy?? Eg. https://en.wikipedia.org/wiki/Proxima_Centauri#Notes 24.78.228.96 (talk) 22:12, 7 February 2021 (UTC) Full disclosure, this is a pointed question: The irradiance/insolation of every new extra-solar planet is easy to calculate yet this information seems to get buried. The Earth's solar constant is the reference comparison. I find these notes downright duplicity in light of that deletionist behaviour. 24.78.228.96 (talk)
 * WP:CALC is the exception to the WP:OR policy that allows for simple mathematics without needing to cite secondary sources. Iffy★Chat -- 22:25, 7 February 2021 (UTC)
