General agreement is observed between the LLAMA measurements and the synthetic diagnostic, including the characteristic asymmetry, trends, and order-of-magnitude. Turbulence plays an important role in transporting particles out of the confined region, which propagates via neoclassical effects in one direction or the other along the magnetic field to provide an asymmetric source of recycled neutrals.
