名前	種類	概要
`Box`	型	A rectangle in the page's pixels, for the boxes a figure's name must stay clear of (`StarNames.labels` are such boxes).
`clampStrength`	関数	A strength held to 0 up to 1.
`CONSTELLATION_LINES_ATTRIBUTE`	定数	The attribute a page offers for the lines, as a settings panel sets it: `constellation-lines`, a strength from 0 to 1.
`CoverMask`	型	How a page says that a spot of its screen is covered by a body in front of the sky (the Earth, a planet, a panel): `true` where a star would not be seen.
`createFigureLines`	関数	The constellation figures as lines for a sky of your own, faint, with the figure under the pointer at full strength and its name.
`createStarNames`	関数	The names of the brightest stars for a sky of your own.
`Culture`	型	A sky culture: a named set of figures.
`DEFAULT_LABEL_STYLE`	定数	The look a name has when nothing is asked for, chosen from several proposals, "Display with catalogue letters": the name in Michroma in small capitals with wide letter spacing, a thin ring round the star, and the star's catalogue letter under it in small monospace.
`DEFAULT_LINE_STRENGTH`	定数	The strength the lines have when a page asks for them and says no more: faint, so that most of the sky is seen without lines.
`designationWidth`	関数	The width a star's catalogue letter (`α Ori`) takes in pixels in the look's small monospace, 0.6 of its size a letter; 0 where it is not drawn.
`discCover`	関数	A mask for a round body, such as the Earth seen from space: every spot within `radius` pixels of its centre is covered.
`FigureLines`	型	The figures of one sky.
`FigureLinesSettings`	型	What the lines are.
`FigureName`	型	The name of the picked figure and where to draw it, centred on `x`, with its baseline at `y`: clear above the figure, and never over a star's name.
`FigureOnScreen`	型	One figure on the screen: where its lines are in `FigureLines.segments`, and its name's spot.
`LABEL_SIDES`	定数	The places a name may take, in the order they are tried: right of its star, left, above, below.
`LABEL_STYLE_PROPERTIES`	定数	The name of the CSS custom property for each part of the look, for a page that styles its labels from a stylesheet.
`labelHeight`	関数	The height a line of text takes in pixels: 1.2 times its size.
`LabelSide`	型	A place for a name.
`labelStyle`	関数	A complete look from a partial one: every part left out or not usable takes its default, and every number is held to its range, so a bad setting never breaks a label.
`LabelStyle`	型	The look of a name drawn on the sky.
`labelStyleFrom`	関数	A look read back from CSS custom properties: any property the page has not set keeps its default.
`labelStyleVars`	関数	A look as CSS custom properties, to set on the element that holds the labels (`element.style.setProperty(name, value)`), so a stylesheet can restyle them as well.
`labelText`	関数	A name with the look's case applied.
`labelWidth`	関数	The width a name takes in pixels, from its length and the look: a Latin letter is about 0.6 of the size wide (0.75 in small capitals, which are wide in Michroma), a Japanese letter the whole size, and the letter spacing is added after each letter.
`lineStrengthFromAttribute`	関数	The strength from the attribute `constellation-lines`, read as text.
`NameLanguage`	型	The language of the names: `en` for the IAU spelling (`Sirius`), `ja` for the katakana (`シリウス`, English where a star has no katakana).
`placeLabel`	関数	Put a name on one side of a star: right, left, above (centred over it) or below (centred under it), with the star's catalogue letter under the name when `designation` is true.
`ScreenPoint`	型	A place on the page's screen, in pixels from its top left corner.
`SkyProjector`	型	How a page says where a star is: it gets the star's right ascension and declination in degrees and writes the spot on its screen into `out`.
`SkyView`	型	The part of the screen names may use, in pixels.
`STAR_NAMES_ATTRIBUTES`	定数	The attributes a page offers for the names, as a settings panel sets them: `star-names` (a count) and `star-names-magnitude` (a limit).
`StarNameLabel`	型	One name to draw: the star, the text with the look's case applied, and where everything goes, in the page's pixels.
`StarNames`	型	The stars' names for one sky.
`starNamesFromAttributes`	関数	Settings from the two attributes a page offers, `star-names` (a count) and `star-names-magnitude` (a limit), read as text.
`StarNamesSettings`	型	What to name.
