1. ISAP HISTOGRAM.
HISTOGRAM Submenu: This is a submenu of the ANALYSIS menu.
If there is an OPEN IMAGE (FILE menu) on the screen,
and a particle has been BLOCK SELECTed (IMAGE menu), then
the HISTOGRAM submenu of the ANALYSIS menu displays
a bar graph of the gray values in the particle.
The RED BARs represent the distribution of gray values.
The BLUE BAR is the arithmetic mean for the distribution
of gray values. The YELLOW BAR is a DIVIDER for a bimodal
distribution, calculated by dividing the histogram at all
possible points along the x-axis, and selecting the minimum
pooled Student t standard deviation.
