True sky view. The observer is at the center of a hemisphere. The program uses a full-screen stereographic sky-map style projection of the visible hemisphere.

Altitude. Smaller conductor curves are closer to the zenith. Larger conductor curves move toward the horizon.

Longitude. Longitude comes from the equalized percentile of frac(log₂ Ω), where Ω is the real period.

Prominence. The largest prime factor of the conductor is emphasized continuously. Curves whose conductor involves only very small primes appear much brighter and larger.

Shape. Torsion controls the geometric star core and ray pattern. Rank controls the main color family. CM curves keep a gold signature.

Controls. Wheel or +/- zooms inside the atlas. Drag pans. Pinch zoom is handled by the atlas on touch screens. 0 resets. Esc closes the panel. Search supports labels, discriminants, j-invariants, Weierstrass coefficient lists, and general cubic equations.
