The Times arrays contain the ‘scan’ or ‘trace’ times at which the raw, FBE and spectrum arrays were acquired or processed:

  • For raw data, these are the times for which all loci in the ‘scanned’ fiber section were interrogated by a single pulse of the DAS measurement system.
  • For the processed data, these are the times of the first sample in the time window used in the frequency filter or transformation function to calculate the FBE or spectrum data.
