hbase HistogramBase
Definition:
The value of the leftmost of the two most populated peaks in a histogram. This
parameter is primarily useful for waveforms with two primary parameter values
such as TTL voltages where hbase would indicate the binary `0' voltage value.
Description:
The two highest histogram peaks are determined. If several peaks are of equal
height the leftmost peak among these is used (see pks). Then the leftmost of the
two identified peaks is selected. This peak's center value (the line that divides
the population of the peak in half) is the hbase.
