== Data Organization ==
The data organization describes the physical meaning of the independent
variable(s) with respect to which the observables are measured. This is
useful for knowing whether and how different data sets can be directly
compared, overlaid, mapped, or otherwise transformed.

The following values are recognized:
''' image '''
data organized by two dimensions corresponding to angular displacement
along the axes; examples include photograms (digital or digitized
photographs), spectroheliograms, magnetograms, and Dopplergrams
''' map '''
data organized by two dimensions corresponding to spatial displacement
along the axes; examples include synoptic charts
''' time_series '''
data organized by one dimension corresponding
to temporal displacement along the axis; note that this is not the
same as a time-tagged set of data records, since it implies sampling
uniformity and provision for data gaps
''' movie '''
data organized by three dimensions corresponding to spatial or
angular displacement along two axes and temporal displacement along
the principal (most slowly varying) axis
''' spectrum '''
data organized by one dimension corresponding to displacement in
electromagnetic wavelength or frequency along the axis
''' mode_spectrum '''
data organized by one or more dimensions corresponding to the quantum
numbers of oscillations
''' spectral_temporal '''
data organized by two dimension corresponding to displacement in wavelength or frequency along one axis and temporal diplacement along the other
''' spatial_spectral '''
data organized by two dimensions corresponding to spatial or angular image axes and one corresponding to electromagnetic spectral displacement
