A numeric list value for quality. This is often the type used to describe a VCV matrix or some other arbitrary list of values. To specify a VCV matrix of 2x2 or 3x3 dimension it is better to use VCV2D and VCV3D respectively.

Often the reference frame and coordinate system of the quality matrix matches that of the coordinates, but sometimes these figures can be provided in a difference coordinate system. For example, coordinates could be in geocentric cartesian coordinates, but the quality could be in topocentric (ENU) cartesian coordinates which thurs requires rotation and translation before propagating variance.

Unknown is used when the parameter values are provided without a source and without an estimate of quality.
enumeration
Approximate
Approximate is used to describe parameters that have been manually or systematically guessed for the purpose of providing operands for a parameter estimation.
