Peak Threshold specifies the level that the signal must exceed to be considered a peak.
Minimum Excursion specifies how much the signal must decrease and then increase
before another peak can be declared.
Density Threshold specifies the signal density (number of hits per displayed pixel) that
the DPX bitmap must exceed to be considered a trigger event.
Minimum Excursion specifies how much the signal density must decrease and increase
again before another peak can be declared.
Smoothing specifies the number of pixels around the marker that are averaged together
to reduce "noise" in the readout of signal density. The value of this control is the number
of pixels on each side of the square area used for averaging. With Smoothing = 1, no
averaging is done and the marker z-axis readout is the hit count (density) of a single
pixel. Use this control to characterize how wide or narrow a range of pixels should be
averaged to determine the signal density.
