19.7.8 DAS Spectra

The DAS Spectra object (DasSpectra) contains the attributes of spectra processed data. This includes the spectra data unit, location of the spectra data along the fiber optical path, information about times, (optional) filter related parameters, and UUIDs of the original raw from which the spectra file was processed and/or the UUID of the FBE files that were processed from the spectra files. Note that the actual spectrum data samples and times arrays are not present in the XML files but only in the HDF5 files because of their size. The XML files only contain references to locate the corresponding HDF files containing the actual spectrum samples and times.

The array types to store the data samples and corresponding times arrays in the HDF files are described in Section 19.8 DAS Array .
