Zapping details

The zapping function allows the user to identify a region of data points in a 2D data object or 3D data object and replace them with a straight line connecting the starting data point with the ending data point at the extremes. In case of 3D data, the specified region is replaced by a plain surface.

While it can be used for many things, this data editing tool is especially useful for wiping out interferences and spikes, before e.g. searching data on a library.

Zapping parameters

The following parameters can be adjusted for zapping:

Applied Axis

This parameter is only available with 3D data objects. It denotes the zapping axis. Either the x-axis or y-axis can be selected for zapping.

What is the maximum zapping region?

The zapping region must not exceed the borders of the current active spectrum. It is not possible to enlarge the zapping region beyond the range of the x-axis of the current active 2D data object.

Minimum

Holds the starting value of the region in the dimension to be zapped.

Maximum

Holds the ending value of the region in the dimension to be zapped.
