starid 1.3.4

star identification

references, about

sky generates a three-dimensional sky model and two-dimensional images from the nasa skymap star catalog, finds stars near arbitrary points on the sky

star triangles recurrently sets aside stars that disagree geometrically until one remains

star patterns are relatively sensitive to rotation

star sequences can be less sensitive to rotation

star languages writes sentences about star patterns using a geometrical language and translates into an identifier language
