* clusters/halo.py: Constrain tau_acc to avoid zero diffusionAaron LI2017-07-232-2/+22
| | | | | | | | | | Zero or negative diffusion coefficient leads to unstable or wrong results due to numerical algorithm/scheme adopted to solve the Fokker-Planck equation. Also add a NOTE to the FokkerPlanckSolver class. Signed-off-by: Aaron LI <aly@aaronly.me>
