FAINT_LEVELS定数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
The tile levels, brightest first. A star lies in the first level whose faintest it does not pass, so level 0 holds everything to magnitude 10, level 1 the stars from 10 to 11 and level 2 those from 11 to 12.
A level's tiles are bands of declination bandDegrees high, each cut into as many tiles along right ascension as keep a tile about as wide as it is tall at the edge of the band nearer the equator.
