<!--
This "label" is intended only to demonstrate how to use certain features of the Spectral
Dictionary, and pretty much nothing else. It is not a real label in any sense, even though
it should produce no errors when validated against the PDS schema. A real label would have
references to additional dictionaries, for example, from the mission, for geometry, and/or
for any other related discipline or local namespaces. Any "data" you see here is fictitious,
and provided merely to remove any validation errors that might otherwise occur.
Note, in particular, that any conscientious reviewer would consider the data structure classes
to be inadequate without appropriate descriptions, extrema, null data indicators, and similar
essential metadata.
This label demonstrates:
- Using <sp:Spectral_Characteristics> for a "3D" array spectrum;
- Using the <sp:Circular_FOV> to describe the aperture; and
- Using the <sp:Spectral_Lookup> class to identify two data objects in the same file that
provide pixel-by-pixel values for bin centers and bin widths. These might be, for
example, "back planes" of a spectral cube.
