    * Concerning flagging, the acceptable size of a gap will become important for using ftime=1 or ftime=2.
+====== GAP INTERPOLATION ======
 The Akima Spline interpolates based on the gradients between points of the nearest neighbours in the time series. At least five neighbours are required (this may be satisfied by having two to three points on either side of a gap). The values of more distant neighbours appear to have little effect on the finally interpolated data.

 For this example we generate our own gaps so that the results may also be compared to the original values.
