The vibration plot data is selected from raw data files "fig2_part1.ChrViewLog" and "fig2_part2.ChrViewLog" (column 6 "Distanz_um") starting at line 999598 from the first file and rolling over to the second. The data was taken at a rate of 2000 Hz.

Every 20th data point is selected (to lessen the calculation time and plotting time) with a total of 1001 used for calculating a mean displacement value. This mean displacement value is subtracted from each data point and time is offset to an arbitrary zero.

The graph generated displays the first 600 data points over a timespan of six seconds and an average displacement of around 4 micrometres to each side.
