Description:
The center value of each populated bin is squared and multiplied by the
the bin. All results are summed and the total is divided by the population of all the bins. The
square root of the result is returned as hrms.

histtop HistogramTop
Definition:
The value of the rightmost of the two most populated peaks in a histogram. This parameter is
useful for waveforms with two primary parameter values, such as TTL voltages, where htop
would indicate the binary `1' voltage value.
Description:
The two highest histogram peaks are determined. The rightmost of the two identified peaks is
then selected. The center of that peak is htop (center is the horizontal point where the population
