Hi jeanett,
I have played around a bit with your data. Not sure it is sufficient and satisfactory,
you can just take this as a hint.
1) Because a spike around X=0 at the lower curve goes horizontally, first I switched
your B as to X, and A as to Y.
2) To remove this spike, I applied the Smooth:Percentile Filter (with Points of
Window = 2, and Percentile = 50)
3) Since there is a zigzag to switch one track to the other, I have masked two
points: #217(-24785.5, 9.54E-4) and #432(at 24087.2 , -0.0011).
4) To make the curve smoother, I have applied Smooth:Adjacent-Averaging
(with Points of Window = 5).
See the result in the screenshot below. The spike was removed by 2), and the curve
is smoother by 4). However, 4) caused the shape of the terminal shortened.
I couldn't avoid this artifact. You may need to do a patchwork with the original
data for the terminal area.
