The <Array_2D_Spectrum> class is a specialization of the Array_2D class. It exists on the assumption that PDS will develop spectrum-specific requirements and software support that will be able to take advantage of assumptions and structures made for this data type.

In fact, this development is going on as I write. It seems likely that this will result in additional classes that will come from a discipline dictionary, and thus will be found outside the array definition in the <Discipline_Area> of the label. These new classes and any associated requirements will likely be included in the next release of the Information Model and schemas (most likely late in 2013).

For an Array_2D_Spectrum, follow the instructions for Filling Out the Array_2D Data Structure, with the following additional contraints/requirements:

  • Use <Array_2D_Spectrum> and </Array_2D_Spectrum> rather than <Array_2D> and </Array_2D>.
