Notes
edit- ^ The given distance in the overview of NED of 133 ± 8.718 megaparsecs (433.8 ± 28.43 million light-years) was based on an estimate using the Tully-Fischer relation. The distance estimate in this infobox was based on the galaxy's redshift.
- ^ a b The quick-look major axis physical diameters given by NED of 110.77 by 86.40 kiloparsecs (361,000 by 282,000 light-years) and 62.67 by 50.14 kiloparsecs (204,000 by 164,000 light-years) were based on a distance estimate of 133 ± 8.718 megaparsecs (433.8 ± 28.43 million light-years). The quoted diameters in this infobox was based on NED's provided scale "Virgo + GA + Shapley" of 973 pc/arcsec multiplied with the given angular diameters.
