(1) Count rate trace
In the Count Rate diagram the count rate(s) (CR) in kHz is plotted vs. running time. If a cross correlation
set-up is used, the count rate trace for each channel is displayed. If you have set an electronic dust filter
in the Measurement tool in Processing, loaded raw data files with an electronic dust filter activated or
placed cut limits manually the cut off regions will be displayed as matted areas.
You can zoom in the diagram by pressing the left mouse button and drawing a rectangle of the area you
want to zoom in. After disengaging the button, the zoom image will be displayed.

• These regions can overlap. Remove cut region will remove the last cut region. By repeatedly
choosing this option, the cut regions in the reverse order of their creation will be removed. Remove
all cut regions will remove all cut regions simultaneously.
The remaining parts of the count rate disrupted by cut out regions will be separately correlated and
the average will be calculated and displayed.
• Copy text to clipboard will copy the diagram coordinates into the clipboard, from which they can be
pasted into other programs like Excel. Write text to file will store the diagram coordinates in a .txt
file. You will be prompted to choose a name and a folder before saving.
• Choosing Abscissa logarithmic or Ordinate logarithmic will display the abscissa or ordinate in a
logarithmic scaling.
• The line width allows you to select the thickness of the graph. Six settings are possible.

By clicking the right mouse button within the
diagram you obtain the Count rate context menu
(Fig. 366).
• If you have zoomed in, you can go to the
original image size by choosing the Reset
diagram zoom option.
• If you have a raw data file available, you can
define cut regions by choosing the New cut
region option. The cut region size can be
adapted by two sliders. The cut out region is
thereby displayed as a matted box (Fig. 295).
You can select independent cut regions for
different channels of a cross correlation
experiments. In cross-correlation calculations, a
cut region in one channel will automatically
define the same cut region in the other
channel. You can select more cut regions by
repeatedly choosing this option.
