Heliographic Frame
A frame effectively represents a snapshot of some appreciable part of the visible disk at a particular time.
All or part of a solar magnetogram remapped to standard heliographic coordinates defines a heliographic frame.
The heliographic frame is a subset of a complete SynchronicMap, i.e., Synoptic Frame or Synchronic Frame, which is constructed by inserting a heliographic frame into a diachronic or synchronic chart.
A series of [:SynopticMap:synchronic frames] can be useful for studying the effects of time evolution of the solar magnetic field in a global context.
