That means that the Traveller-style Universal Planetary Profile (UPP) shorthand is used in the following pages. It takes the form of a eight character code indicating, in order: Star/space port, size, atmosphere, hydrographics, population, government, law level and tech level. Note that in most cases, extra data mapping the Traveller code to the corresponding Space Opera value will be provided in notes. All tech levels are Space Opera. The UPP, thus, is only a first-order approximation.
