update parameterization to fit : 1-erf(H/Lz) = c1 * β/βt + c2.
update parameterization to fit : 1-erf(H/Lz) = c1 * β/βt + c2.

Notes:
1. The earlier exponential like pattern was fake. It is sensitive to amount of smoothing.
2. Theory indicates that I want a linear relationship (since erf is generally a straight line).
