Detailed Description

Creates a collection of space points.

A collection of space points is added to the event. The points are spaced by the value of the spacing configuration parameter, in a cubic grid. Each TPC is independently filled, so that the TPC centre hosts a space point.

The space points are not associated to anything.

Configuration parameters

• spacing (real, mandatory): spacing between the points [cm]
