Measurements for some or all Annotations in the Annotation Group. Each Item describes one type of measurement.
See Section C.37.1.2.1.2.
One or more Items are permitted in this Sequence.
For each Annotation Group, optionally one or more measurements may be defined, either for every Annotation or a subset of Annotations. Measurements are described by coded type and unit.
When there is a measurement for every Annotation, then Floating Point Values (0066,0125) contains the corresponding values for each of the Annotations. When there are measurements for only a subset of Annotations, then Floating Point Values (0066,0125) contains measurement values for the Annotations that are referenced in Annotation Index List (006A,0011).
More than one Measurements Sequence (0066,0121) Item may be used, for example to encode different types of measurements, or to encode different components of a measurement that is a tuple.
Within one Annotation Group the types of measurements are the same for all Annotations within that group.
