-Flag to turn on pitch angle diffusion. The default setting for the Kp-based version uses Kp=0 coefficients. Turning this flag on interpolates Kp-dependent diffusion coefficents for Kp in the range (0-4). Different options are available if selecting DoUseBASDiff. EMIC wave pitch angle diffusion is used for ions wave-particle interaction.
