註解
[编辑]- ^ The given distance in the overview of NED of 133正負8.718百萬秒差距（433.8正負28.43 × 106光年） was based on an estimate using the Tully-Fischer relation. The distance estimate in this infobox was based on the galaxy's redshift.
- ^ 2.0 2.1 The quick-look major axis physical diameters given by NED of 110.77乘86.40千秒差距（361,000乘282,000光年） and 62.67乘50.14千秒差距（204,000乘164,000光年） were based on a distance estimate of 133正負8.718百萬秒差距（433.8正負28.43 × 106光年）. 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.
