Hello David,

I have looked into this and I think the reason I decided that the
constants needed changing is that the js_demo program reports the
input range for axis 3 to be +0.4 (0%) to -0.6 (100%) i.e. the span is
only 1 rather than 2 as you suggest below.

The ranges of the other axis are:

 axis0 = -0.5 -> +0.9
 axis1 = +0.6 -> -0.8
 axis2 = -0.6 -> +0.6

Cheers,

Mark
