Median	The value that is situated in the middle when the values are ordered by size.
RMS	Root mean square.
StdDev	Standard deviation.
Max	Largest value.
Integral	Integral.
Min Δt [s]	Smallest change of time intervals for successive values.
Avg Δt [s]	Average change of time intervals for successive values.
Median Δt [s]	Median change of time intervals for successive values.
StdDev Δt [s]	Standard deviation of change of time intervals for successive values.

Action	How to be performed
Sorting the table by a column	Click the heading of a column of the table. Result: The table is sorted by that column and changes the order from ascending to descending and back. By default, the table is sorted in ascending order by the Index column. Thus, the signals are sorted in the same order as in the tree structure.
Selecting a line	Click a line to select it. To select or clear several lines, press Shift + the up arrow or down arrow key.
Copying selected lines	If you have selected one line or several lines, press Ctrl+C to copy the selection to the Clipboard. The values of the individual columns are tab-separated, and the lines are delimited with the control character CR or LF.
