Other objects can be observed using CCD cameras or photoelectric photometers connected to a telescope, and the ''flux'', or amount of light received, can be compared to a photometric-standard star to determine the exact brightness, or stellar magnitude, of the object. The current set of photometric-standard stars for UBVRI photometry most often used by astronomers is that published by Arlo U. Landolt in 1992 in the Astronomical Journal, vol. 104, no. 1, p. 340-371. 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「Photometric-standard star」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.
