At 53% similarity, the sun-grown coffee site 4 (SUN4) is separated from the other SUN sites ([pi] = 7.96, P < 0.05) and at 64.9% similarity, it is apparent that the shaded coffee plantations constitute a significantly separate group from the exposed coffee plantations ([pi] = 6.9, P < 0.05), but shaded coffee site 8 exhibits no differences from the exposed coffee plantations.

In one study, the researchers took photographs of partly cloudy or twilight skies in northern Finland through a 180-degree fisheye lens, and asked test subjects to estimate the position of the Sun4. Errors of up to 99 degree led the researchers to conclude that the Vikings could not have relied on naked-eye guesses of the Sun's position.
The subsystems are written in C and run under SunOS on the Sun4 platform.
All the examples are executed on a standard SUN4 workstation.
We have measured the time taken by the steps described in Section 4 on WSJ on a SUN4 workstation.
