The following diffusion values were calculated by Blair Stringfellow
using **Magboltz 1** (Biagi, 1995). The assumed temperature and
pressure were similar, if not identical, to the STAR operating
conditions (~2 mbar above the ambient atmospheric pressure with
**E** ~ 148 V/cm and **T** ~ 75F=23.9C) .
