galaxyDistance関数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
The distance to a Messier galaxy: the median of the distances Wikidata (CC0) gives, in light-years and parsecs, with the error where a statement has one, the lowest and highest statement, how
many there are and whether they disagree (the highest more than 1.2 times the lowest). The method is always "compiled, method not stated": Wikidata gathers published values and names no method.
This table holds the Messier galaxies only; for the NGC and IC galaxies use galaxyDistance from @johnmorrisdotca/hoshi-stars/deep-sky/ngc-ic.
