27 of its payloads in orbit have no public path: the catalogue lists them, but no element set is published for them, or they are beyond Earth orbit. The map lists them and says which.
Shared with another country, and not counted above: Singapore and Japan (0 in orbit, on the map).
Measured. The counts are the catalogue's: what radar can track, about 10 cm and up, on the day given. A satellite's place on the map is worked out from its published orbit.
