Recognizing stars in photographs with no metadata

Canonical description of a triangle that is invariant under translations, rotations, and dilations? A moduli space.

I will provide a function that takes the coordinates and IDs of the stars and galaxies from your patch, and gives you back the coordinates of a part of it after dilating, rotating and translating. Your goal is to recover the IDs of the objects whose transformed coordinates are returned.
