距離で見る空 (10・50・100・500・1,000光年より近い星や銀河を層に分けて、距離の帯ごとに色分けします。距離がはっきりしないものは別にし、推測で置くことはしません)

名前	種類	概要
`bandOf`	関数	The band of a distance: 0 under 10 light-years, 1 under 50, 2 under 100, 3 under 500, 4 under 1,000 and 5 beyond (a distance of exactly the edge is in the nearer band).
`Certainty`	型	How well a distance is known: `good` (under 5%), `fair` (5% to 20%) or `rough` (over 20%, or no error stated).
`CERTAINTY_LIMITS`	定数	The relative errors that divide a distance's certainty, the same as `QUALITY_LIMITS` of the constellation in 3D: a parallax known to under 5% is `good`, to 20% is `fair`, and worse (or with no error stated) is `rough`.
`certaintyOf`	関数	The certainty of a parallax known to a relative error (the error over the parallax): `good` under 5%, `fair` up to 20%, `rough` over it.
`deepSkyInput`	関数	A deep-sky object with a galaxy's distance (`galaxyDistance` of `/deep-sky`) as a thing with a distance.
`DISTANCE_ATTRIBUTE`	定数	The attribute a page offers for the limit, as a settings panel sets it: `distance-limit`.
`DISTANCE_LIMITS`	定数	The limits the sky map steps through, in light-years: 10, 50, 100, 500 and 1,000.
`DistanceInput`	型	Something with a place on the sky and perhaps a distance, as `layersByDistance` takes it.
`DistanceLayers`	型	What `layersByDistance` gives back.
`LayeredThing`	型	A thing in a layer: where it is, how far, and which band it is in.
`LayerKind`	型	The kind of thing in a layer: a bright star of the Yale catalogue, a nearby star of the Yale parallax catalogue (`/nearby`), or a deep-sky object with a distance (a galaxy).
`layersByDistance`	関数	The things out to a limit, each in the band of its distance.
`limitAtSlider`	関数	The limit at a slider's position, 0 to 1, on a scale where each step is the same ratio (4 light-years to 3 million).
`limitFromText`	関数	The limit from the attribute `distance-limit` (and the address's `dist`), read as text: a number of light-years, or `all`.
`limitText`	関数	A limit as the text the address keeps: `all`, or the light-years rounded (to the step where it is a step, else to 2 significant figures).
`nearbyInput`	関数	A nearby star (`/nearby`) as a thing with a distance.
`SLIDER_RANGE`	定数	The nearest and farthest limits a free slider reaches, in light-years: from Alpha Centauri's neighbourhood to past the Andromeda Galaxy; beyond the last is `all`.
`sliderOfLimit`	関数	Where a limit sits on the slider, 0 to 1; `all` is 1 and a limit under the slider's start is 0.
`starInput`	関数	A bright star of the Yale catalogue as a thing with a distance, from its parallax and its error.
`stepLimit`	関数	The next limit up or down the steps (10, 50, 100, 500, 1,000, then all).
