About the Example Labels

These “Demo” files provide simple demonstrations of how to use the Spectral dictionary to describe a variety of spectral formats and bin description techniques. They have been designed to pass simple validation, so that they can be used as a starting point for development and testing. Note, however, that these are far from being complete labels in any sense. In particular, the data structures would not be considered “complete” by any conscientious reviewer without significant additional metadata - like field descriptions, ranges and extrema, and so on.

The demo labels include:

• 1D spectrum, using <Spectral_Lookup> to reference table fields, complex FOV

• 1D spectrum, using <Uniformly_Sampled>, rectangular FOV

• 2D spectrum, using <Uniformly_sampled>, rectangular FOV

• 3D spectrum, using <Axis_Bin_Set>, rectangular FOV

• 3D spectrum, using <Spectral_Lookup> to reference data objects in the same file, circular FOV

• Tabulated-Flat spectra, using <Spectral_Lookup> to reference another product for bin centers and to specify unknown bin widths, rectangular FOV

• Tabulated-Flat spectra, using <Spectral_Lookup> to reference fields using a list of field numbers, circular FOV

• Tabulated-Parameter Groups spectra, using <Spectral_Lookup> to reference fields in Group_Field classes, rectangular FOV

• Tabulated-Point Group spectra, using <Spectral_Lookup> to reference fields in a Group_Field class, complex FOV

• Tabulated-Point Group spectra, using <Spectral_Lookup> to reference a field in a Group_Field class for bin center, and <Bin_Width_Constant> for bin width, complex FOV
