deepSkyShape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 size, axis ratio and angle of a Messier object on the sky. For a galaxy they are RC3's (the major axis at the 25th magnitude isophote, the axis ratio and the angle) or, where RC3 has none,
NASA/IPAC NED's; for any other Messier object, and for a galaxy with neither, the one diameter that the object's own row carries (sizeArcmin), with no ratio and no angle. Every part is a
measurement or undefined; the sources are in NOTICE.md.
