This document defines the high level metadata necessary to describe
the physical parameter space of observed or simulated astronomical
data sets, such as 2D-images, data cubes, X-ray event lists, IFU data,
etc.. The Characterisation data model is an abstraction which can be
used to derive a structured description of any relevant data and thus
to facilitate its discovery and scientific interpretation. The model
aims at facilitating the manipulation of heterogeneous data in any VO
framework or portal.
A VO Characterisation instance can include descriptions of the data
axes, the range of coordinates covered by the data, and details of
the data sampling and resolution on each axis. These
descriptions should be in terms of physical variables, independent of
instrumental signatures as far as possible.
