Type Alias: PackedBody

type PackedBody = "chiron" | "pluto";

Default chart bodies that can be Chebyshev-packed, so they can fall outside a pack's fitted range (and be omitted from a chart). Chiron is always packed; Pluto is packed when the wide-range pack is loaded (the Meeus fallback otherwise always resolves, but the type must cover the packed engine, where an out-of-range Pluto lands in Chart.unavailable). Opt-in asteroids are packed too, but arrive as arbitrary ids through the string index.
