Does FFSAR use a 50% threshold retracker? Does it linearly interpolate between waveform bins?

To better understand how the FFSAR processor works:
- Does the processor use a 50% threshold retracker?
- Does the processor linearly interpolate between waveform bins?

FFSAR uses a 60% threshold and it inlcudes an implementation of the following retracker: Davis C. H., "A robust threshold retracking algorithm for measuring ice-sheet surface elevation change from satellite radar altimeters," in IEEE Transactions on Geoscience and Remote Sensing, vol. 35, no. 4, pp. 974-979, July 1997, doi: 10.1109/36.602540.
