r is for radius, synonym for distance. I've been using the [pow -2] object 
to convert distance to amplitude, but apparently that's wrong, i have to 
add a square root object like [pow 0.5] because [pow -2] is the formula 
for distance to energy. Both pow objects can be merged together as one 
[pow -1] object.
