It was described in 1970 by Ken Freeman.〔McGaugh et al., "(Galaxy Selection and Surface Brightness Distribution )" (1995) ''Astronomical Journal'', 110 (1995) 573,〕 The Freeman law was confirmed in year 2010 for a sample of 30000 Sloan Digital Sky Survey galaxy images 〔Kambiz Fathi, "(Revisiting the Freeman Law in the Local Universe )" (2010) ''Astrophysical Journal'', 722 (2010) L120,〕 and it can be used with the Tully-Fisher relation to determine the luminosity and therefore distance of an observed galaxy. However more recently it has been argued that the Freeman law is an effect of selection bias.〔〔Minnesota State University, "()"〕 ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Freeman law」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
