Order parameter in Mesocite

Hi,

I have used the script made by Reinier Akkermans for calculation of order parameter in Mesocite. (https://community.accelrys.com/message/7645#7645)

I have a few questions about the script.

I will illustrate the order parameter in my thesis.

First,

I don't know what "r" means for the following equation,

If a density filed is calculated, isn't it 3-dimensional properties?

I want to know about the local density as a function of r.

Sencond,

I want to know the process of conversion for density field, approximatively.

It is really fine with a breif explains.

Many Thanks
