extends Observation

A derived observation is an observation created from one or more other observations. Examples of multiple members include: stacks of images combined to increase signal:noise ratio, mosaics combined to increase field-of-view, etc. Examples of single members: subset of comensurally observed data that is attributed/assigned to one proposal or project (with associated permissions).

Members

name type mult description
members ivoa:anyURI 0 or more The members are the observations grouped together by the algorithm that defines the derivation. these are the intended components of the composite product, but actual inputs are described by the provenance. Members may be simple or derived observations (arbitrary heirarchy); derived observations with one or more members may be defined such that they only include a subset of each member (they are extracted from the progenitor). Observation.uri values are used here to refer to the member observations.
