<!--
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 "1D" table spectrum;
- Using the <sp:Complex_FOV> to describe the aperture; and
- Using the <sp:Spectral_Lookup> class to identify bin centers and widths as fields in
the table.

<!-- Spectral Lookup for 1D spectrum (table), in Table fields -->

<comment>
The spectral bin centers are included in the table in the named field. In
this case, FWHM values are also included in the table as a separate field.
Table field classes must have 'name' attributes (although these are not
currently required to be unique).

<sp:Field_of_View>
<sp:description>
This field of view is not a regular shape. Typically this should be
described in some detail in a document that is referenced within this
class (we'll assume one exists in this case as a demonstration). For
example, the Alice spectrometer on New Horizons has a "lollipop" shaped
slit. I don't know the actual dimensions of that slit, so the
description below is fake. This description would specify how the
'width' value indicated here correspond to the slit design, for example.

This document provides both a diagram and specific physical
measurements of the lollipop-shaped slit.
