19.8.3 DAS Spectra Data

Three-dimensional array (loci, time and transform) containing spectrum data samples. Spectrum data is processed data obtained by applying a mathematical transformation function to the DAS raw data acquired by the acquisition system. The array is 3D and contains TransformSize points for each locus and time for which the data is provided. For example, many service providers will provide Fourier transformed versions of the raw data to customers, but other transformation functions are also allowed.
