extends AEDF

Feed charactersitics.

A feed is a collecting element on an antenna, such as a single horn, that shares joint physical properties and makes sense to calibrate as a single entity. It is an abstraction of a generic antenna feed and is considered to have one or more RECEPTORs that respond to different polarization states. A FEED may have a time-variable beam and polarization response. FEEDs are numbered from 0 on each separate antenna and for each spectralwindowId. Consequently, number should be non-zero only in the case of feed arrays, i.e. multiple, simultaneous beam on the sky at the same frequency and polarization.
