In case the measurements are averaged over a time interval, this node is the full width of this time interval (empty otherwise). In case the slicing/averaging method doesn’t use a hard time interval cutoff, this width is the characteristic time span of the slicing/averaging method. By convention, the time interval starts at time_measurement-time_width and ends at time_measurement.

In case the measurements are averaged over a time interval, this node is the full width of this time interval (empty otherwise). In case the slicing/averaging method doesn’t use a hard time interval cutoff, this width is the characteristic time span of the slicing/averaging method. By convention, the time interval starts at time_measurement-time_width and ends at time_measurement.
