19.5 Defining the DAS Acquisition Data (Raw and Processed Data)

One DAS acquisition job may consist of many data arrays, including both raw and processed (FBE and spectra) data. Because DAS arrays are so large, HDF5 is used to store and manage the measurement data arrays.

NOTE: DAS arrays may be so large that they are split across multiple HDF5 files. XML is used to store all the metadata, and this metadata is repeated in the HDF5. Comments below about metadata refer to both formats.
