名前種類概要
Dot型One dot of a sheet: a star, where it is on the page and the numbers it carries (a star the lines pass again has more than one).
DOT_LEVELS定数How hard a sheet is: easy joins only the brightest 5 to 10 stars of the figure, medium joins every star of its lines, and hard has the same dots with no numbers to find.
DOT_LIMITS定数The smallest and largest radius, in millimetres, a dot of a sheet can have: the floor still prints and can be seen, the ceiling is what the brightest star gets when nothing is near it.
DotLevel型One level of a sheet: easy, medium or hard.
dotsFigure関数A constellation laid out as numbered dots on a page widthMm by heightMm: the stars placed by a stereographic chart, east to the left as in the sky, made as large as fits; the dots sized by brightness and never more than a third of the distance to the nearest dot (DOT_LIMITS), and two stars too close for the smallest dots moved apart to the distance they need; every visit numbered along the lines in drawing order (one number for each time the pencil reaches a star, a star met again carrying both numbers); each number put where it touches no dot, line or other number.
DotsFigure型A figure laid out on a page of a given room.
dotsSubtitle関数The meaning of a constellation's name, for the line under its title: Orion: the Hunter, or its reading in hiragana.
dotsSvg関数One page of a connect-the-dots sheet as an SVG string measured in millimetres: the dots (and the numbers, unless the level is hard), the words that say what to do, and on an answer page the lines too, 1 mm thick for the kid type (0.4 mm for normal).
latitudeBand関数A band of ten degrees of latitude as words: 40° to 50° N or きた 40〜50ど.
monthName関数The name of a month.
RegionEntry型One constellation as a place sees it.
regionGuideSvg関数The sheet "constellations for where you live" as an SVG string measured in millimetres: the constellations always up at a latitude, the best of the evening sky in a month (about 21:00 by the Sun) and the ones never seen, each with its figure and name, and a note on the most famous.
skyForLatitude関数Every constellation as a place at a latitude sees it, best known first: always up (every star of its figure above the horizon all night, all year), never seen (no star of its figure ever rises) or seasonal, with the month it is highest in the evening sky (about 21:00 by the Sun on the 15th) and how high it climbs.
skyMapSvg関数The evening sky of a month over a latitude as an SVG string measured in millimetres: the stars to magnitude 3.2 (kid) or 4.5 (normal) above the horizon, the figures, the names of the best known constellations that are up, N, E, S and W round the horizon, and the words that say how to hold it.
Standing型How a constellation stands at a latitude: always above the horizon (circumpolar), never seen from there, or season (up for part of the night and part of the year).
starWheelDisc関数The star disc of a wheel for a latitude as an SVG string measured in millimetres: the stars to magnitude 3.5 (kid) or 5 (normal), the figures, the equator and the ecliptic dashed, the names of the best known constellations and the ring of dates.
starWheelPlate関数The window plate of a wheel for a latitude as an SVG string measured in millimetres: the horizon as a window, N, E, S and W round it, and the hours round the edge (12 at the top).
starWheelPoster関数A wheel to cut out of a big poster: the disc and the plate side by side, as one SVG string measured in millimetres, diameterMm across each.
WHEEL_LATITUDES定数The latitudes a wheel is made for: 20 to 70 degrees from the equator, north or south.
whyFamous関数A short reason a constellation is worth finding, for the few that have one, else undefined.
