  * Pulse length (sampling rate) should be chosen based on the maximum height of targets in the area. E.G. if all low lying targets then there is no point using 256 samples at 1 ns - better to use 128 at 1 ns.
  * No changes to the calibration flights except to collect FW data. Only change to the processing is to find the timing offset between FW and discrete points.
+ * Pre-trigger - like a buffer zone to record digitised samples before the first return. Default is 5m.

   * .SUP file will automatically offset to the mirror centre in ALSPP processing
   * Unsure as to whether leverarms need to be updated in IPAS or not - also how do we know IMU offsets to apply?

+ * To process full waveform data in ALSPP - Select "process waveform data" from the inputs menu and tick the box. Enter the "Trigger Delay" - this is the time offset between discrete and waveform data.
+ * ALSPP looks for the "RawWfd" folder - this may imply that renaming the directory structure could cause problems.
