starsInside関数
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 catalogue stars (magnitude 6.0 and brighter) that lie inside the circle of an object's major diameter, brightest first. This says where a star is, not what it belongs to: a star in front of a cluster or far behind it is in the list too, because the catalogue gives no cluster distance to tell them apart. Draw them as "inside the outline", not as proven members.
