英語の意味

The apparent angular elevation of the heavenly bodies above their true places, caused by the refraction of the rays of light in their passage through the Earth's atmosphere.

このボタンはなに？

Astronomers must correct for atmospheric refraction when measuring the precise positions of stars, because the Earth's atmosphere bends starlight and makes celestial objects appear higher than they truly are.

天文学者は、地球の大気が星の光を屈折させて天体の見かけの高度を実際より高く見せるため、星の正確な位置を測定する際に大気屈折を補正しなければならない。
