GalacticPointtypeA point in galactic coordinates, in degrees.
MilkyWayBandtypeEverywhere the Milky Way is brighter than one level.
milkyWayBandsfunctionThe Milky Way cut at some brightness levels, as ribbons of sky points for drawing soft bands (a polygon per strip, filled with a low opacity so the levels build up).
MilkyWayBandsOptionstypeWhere to cut the bands, and how finely.
milkyWayBrightnessfunctionHow bright the Milky Way is toward a point, as a display value from 0 (dark sky) to 1 (the brightest part of the core, in Sagittarius).
MilkyWayStriptypeA ribbon of the Milky Way at one brightness level: two chains of sky points of the same length, the upper edge and the lower, each pair at the same galactic longitude.
SkyPointtypeA point on the celestial sphere, in degrees.
toGalacticfunctionThe galactic longitude and latitude of a point of the sky (J2000, the IAU's galactic frame).
@johnmorrisdotca/hoshi-stars/skygreenwichSiderealTimefunctionThe Greenwich mean sidereal time: how far the Earth has turned against the stars, as the right ascension on the meridian of Greenwich, in degrees (Meeus 12.4, the IAU 1982 expression).
horizontalfunctionWhere a star (or any J2000 position) stands in the sky of a place on Earth at a moment: its altitude above the horizon and azimuth from north through east.
HorizontaltypeWhere a star or a planet is in your sky: degrees above the horizon (negative below it) and degrees round from north through east.
horizontalFromfunctionWhere a star stands in the sky of a place on ANOTHER planet: the sky turns about that planet's pole (the IAU WGCCRE pole and prime meridian, passed in as spin), so the star is rotated into the planet's own equatorial frame, its hour angle is the prime meridian plus the observer's east longitude minus its right ascension there, and the horizon formulas are the same as for Earth.
HorizontalOptionstypeHow to read the position and whether to bend the light.
isAboveHorizonfunctionWhether a position is above the horizon of a place at a moment (altitude greater than 0).
localSiderealTimefunctionThe local mean sidereal time: the right ascension that is on your meridian, due south or north of you, in degrees.

precessfunctionA J2000 position carried to the mean equator and equinox of a date: the precession of the Earth's axis (Meeus chapter 21, the rigorous method with the IAU 1976 constants, good for a few centuries either side of 2000 to far under an arc-second).
SkyPointtypeA point on the celestial sphere, in degrees.
@johnmorrisdotca/hoshi-stars/nearestnearestfunctionThe things nearest a star, a deep-sky object or a point, nearest first.
NearestInSkytypeOne answer of a query by angle: the thing and its angle from the target, in degrees.
NearestInSpacetypeOne answer of a query by distance in space.
NearestListtypeA list of answers, nearest first, with skipped: how many candidates had no usable distance and so were left out of a query by: "space" (a parallax of 0 or less, or a deep-sky object).
NearestOptionstypeThe options of nearest and within.
NearestTargettypeWhere a query starts: a star, a deep-sky object, a name starByName or deepSkyObject (the Messier objects) finds, or a point in J2000 degrees.
NearestThingtypeSomething a query can find: a bright star, a nearby star (from /nearby, passed in among) or a deep-sky object.
neighbouringConstellationsfunctionThe constellations that share a piece of boundary with one constellation, in alphabetical order of their Latin names.
withinfunctionEverything within a radius of a target, nearest first: nearest with no count limit and within set to the radius.
@johnmorrisdotca/hoshi-stars/nearbyNearbyFlagstypeWhat to be careful about for one star.
NearbyMagnitudeKindtypeThe kind of a V magnitude in the Yale catalogue: a photoelectric V, a visual or other magnitude of lower accuracy, or a photographic blue one.
NearbyPositionSourcetypeWhere a star's position comes from: a 2MASS source found for it (good to a fraction of an arc-second), or the Yale catalogue's own position (taken to J2000 from 1900, good to arc-seconds at best, an arc-minute at worst).
NearbyStartypeOne nearby star, as the Yale General Catalogue of Trigonometric Stellar Parallaxes gives it, with a 2MASS position where there is one.
nearbyStarByNamefunctionA nearby star by a name, ignoring case: its common name (Proxima Centauri), a name the catalogue gives it (G 158-027), its designation (33 Psc), GJ 551 or Gliese 551, HD 95735, GCTP 2576 or its 2MASS designation (with or without 2MASS J).
nearbyStarsfunctionThe nearby stars, nearest first (the ones with no distance last).
@johnmorrisdotca/hoshi-starsblackBodyColourfunctionThe colour of a black body at a temperature, as a #rrggbb string, for drawing a star.
StartypeOne star, as the Yale Bright Star Catalogue gives it.
starByHrfunctionA star by its Bright Star Catalogue number.
starByNamefunctionA star by its common name (Sirius), its name in katakana (シリウス) or its designation (α CMa, 9 CMa), ignoring case.
starColourfunctionThe colour to draw a star: from its B-V index, or a plain white where the catalogue has none.
starDistanceLightYearsfunctionA star's distance from its parallax, in light-years.
starPositionfunctionWhere a star is at a moment: its J2000 position carried forward (or back) by its proper motion in a straight line.
starsfunctionThe stars to a magnitude, brightest first.
starTemperatureKfunctionThe surface temperature a colour index implies, in kelvin, by Ballesteros's relation between B-V and a black body.
WhentypeA moment: a Date or a number of milliseconds since 1970 (UTC, as JavaScript counts).
