名前種類概要
deepSkyRow関数The row of a deep-sky object.
findName関数The row of the small chunk that a name, a designation or an id names exactly, ignoring case, spacing, accents and the Greek letter's spelling (Betelgeuse, alpha Ori, HR 2061, M31, NGC 224, ベテルギウス), or undefined.
NAME_KINDS定数The kinds of row in the names index: star, cluster (open and globular), nebula (emission, reflection, planetary, supernova remnant), galaxy and other (an asterism, a double star Messier listed, a source that is none of those).
nameIndex関数An index over rows: by id, by exact name and by a ranked search.
NameIndex型What an index of rows offers: the rows, one by id, one by any name, and a ranked search.
nameKey関数A text folded to compare, as findName does: lower case, no accents, Greek letters spelt out and one space, a superscript as its digit; M 31, Messier 31 and m31 give m31, NGC 0224 gives ngc224, HR 2061 and hr2061 give hr2061.
NameKind型One kind of row: star, cluster, nebula, galaxy or other.
NameRow型One row of the names index: a star or a deep-sky object with the names a search box would try, and where to turn the sky to it.
nameRowById関数One row of the small chunk by its id (betelgeuse, m31): the same row /names gives for that id; undefined for a star without a common name (alpha-centauri, hr-1234), which is in /names.
nameRows関数The rows of the small chunk: the 335 stars with a common name and the 110 Messier objects (445), brightest and best-known first (by weight), as a fresh array.
searchNames関数The rows of the small chunk whose names match what was typed: those with a name that starts with it first (an exact name before those), then those that contain it, each by weight.
slugOf関数An address-safe id from a text: lower-case ASCII letters and digits in runs joined by one hyphen; an accent is dropped (Boötes gives bootes) and a Greek letter is spelt out (α1 Centauri gives alpha1-centauri).
