名前	種類	概要
`CatalogueRead`	型	What `readCatalogueRecords` found: the records that can be used, and how many were left out (a number missing or not a number, or an orbit that is not an ellipse).
`CatalogueRecord`	型	One object of the catalogue: its element set (the OMM numbers every source serves), what kind of object it is, and what the catalogue says of its owner and launch.
`CLASS_COLOURS`	定数	The colour of each class on a dark background: green, yellow, red, violet and grey.
`CLASS_LABELS`	定数	The words for each class, in English and Japanese, with the rule that makes it (heights above the mean Earth radius).
`CLASS_LIMITS`	定数	The numbers behind the classes: the highest point a low orbit may have (2,000 km), the eccentricity from which an orbit is highly elliptical (0.25), and how far from 35,786 km the lowest and highest points of a geostationary orbit may be (1,500 km).
`classOfElements`	関数	The class of an orbit straight from the two numbers every element set has, its mean motion (revolutions a day) and its eccentricity; `null` when they are not an orbit.
`countFleets`	関数	How many of each fleet a list of objects holds, and how many objects there are in all: what a filter shows as "N of M".
`Fleet`	型	A fleet: a group of satellites that belong together, found by the pattern its members' names follow.
`fleetOf`	関数	The fleet an object belongs to, from its name and kind, or `undefined`.
`FLEETS`	定数	The fleets, in the order a filter lists them.
`GEO_ALTITUDE_KM`	定数	The height of the geostationary orbit above the equator, in kilometres: the radius of a circular orbit that goes round once a sidereal day (42,164 km) less the equatorial radius (6,378 km).
`gzipBytes`	関数	Gzip bytes, with the web's own `CompressionStream`: the form a site hosts a packed file in.
`KIND_COLOURS`	定数	The colour of each kind on a dark background: cyan payloads, orange rocket bodies, grey debris and pale unknowns.
`KIND_LABELS`	定数	The words for each kind, in English and Japanese.
`legend`	関数	The legend for colouring by class or by kind, in the page's language.
`LegendEntry`	型	One line of a legend: what it is called, in the page's language, and its colour.
`MAX_PACKED`	定数	The most records one packed file holds: the data door's own limit, 200,000.
`MAX_PACKED_BYTES`	定数	The most bytes a packed file may unpack to (64 MB): a file that claims more is refused before it is read.
`OBJECT_KINDS`	定数	The four kinds, in the order a legend lists them.
`ObjectKind`	型	What a catalogued object is: `PAY` a payload (a satellite or probe), `RB` a rocket body, `DEB` debris, `UNK` unknown.
`ORBIT_CLASSES`	定数	The five classes, in the order a legend lists them.
`orbitClass`	関数	The class an orbit falls in.
`OrbitClass`	型	The class of an orbit: low (`leo`), medium (`meo`), geostationary (`geo`), highly elliptical (`heo`), or `other` for what fits none of them.
`orbitShape`	関数	The shape of an orbit from the two numbers every element set has: its mean motion (revolutions a day) by Kepler's third law, and its eccentricity.
`OrbitShape`	型	The size and shape of an orbit.
`OWNER_COUNTRIES`	定数	Every owner code of the satellite catalogue with its country as an ISO 3166-1 alpha-2 code, or `null` where the owner is not one country: an organisation (`ESA`, `ISS`, `ITSO`, `SES`, `GLOB`, ...), several countries (`FGER`, France and Germany; `PRES`, China and ESA), not known (`UNK`, `TBD`), or not one country (`CIS`, the former Soviet registration).
`ownerCountry`	関数	The country of a satellite's owner code as an ISO 3166-1 alpha-2 code (`PRC` is `CN`, `PAKI` is `PK`, `US` is `US`), or `undefined` for an organisation, several countries, an ambiguous owner or a code that is not in the list.
`packCatalogue`	関数	Pack catalogue records into one file: a small header (the format, how many records, and `meta`, a few words of text such as where the data is from and when it was retrieved), a column for each number and, last, the names.
`PackedCatalogue`	型	A packed file, read: the columns as typed arrays (nothing is copied into objects until you ask) and the names.
`PackError`	クラス	A packed file that cannot be read: it is not a packed file, it is cut short, it holds more than `MAX_PACKED` records, or it unpacks to more than `MAX_PACKED_BYTES`.
`RadarSize`	型	The radar size class Space-Track gives an object: small (under 0.1 square metres), medium or large (over 1).
`readCatalogueRecords`	関数	Read catalogue records from OMM text, as JSON (a list of objects) or CSV (a header row, then a row for each object).
`readKind`	関数	The kind a source's object type means: Space-Track says `PAYLOAD`, `ROCKET BODY`, `DEBRIS` or `TBA`, other lists say `PAY`, `R/B`, `DEB` or `UNK`; any other word, or none, is `UNK`.
`unpackAny`	関数	Read a packed file whether or not it is gzipped (gzip is found from its first two bytes).
`unpackCatalogue`	関数	Read a packed file (not gzipped: see `unpackAny`).
