How the map draws it
Drawn from published dimensions for Andromeda, as a model of her own measured shape · tilted as measured, 77° with the north-west edge nearest; her bulge, disc, ring and dust rings follow published measurements, her arms’ exact shape and her stars are ours: points standing for light, not a map of her stars.
