Contents

Reference · A constellation in 3D: its stars placed in space from their parallaxes, with the range each error allows and the Earth's lines of sight

DistanceQualitytype

How well a star's distance is known, from its parallax and the error the catalogue states: good (the error is under 5% of the parallax), fair (5% to 20%, or a dynamical parallax from a binary's orbit), rough (over 20%, or a parallax with no stated error) and none (no parallax: the distance is unknown).

Import it

import type { DistanceQuality } from "@johnmorrisdotca/hoshi-stars/constellation-3d";

Definition

type DistanceQuality = "good" | "fair" | "rough" | "none";

Examples

const kinds: DistanceQuality[] = ["good", "fair", "rough", "none"];
console.log(kinds.join(", "));
good, fair, rough, none
