Figure 5: Calibrated DTS temperatures with different calibration schemes applied to the field data set. (a) Temperature along the entire cable, uncorrected calibration. (b) Temperature along the entire fiber, corrected calibration. (c) Scatter plot of reference and calibrated temperatures in the middle of the cable, uncorrected calibration. (d) Scatter plot of reference and calibrated temperatures in the middle of the cable, corrected calibration.
