ZDD - [G] Half-Gaussian Modified Gaussian (GMG)
This is the Zero Distortion Density (ZDD) used in the GenHVL[G] models. This GMG a1 center parameter is the mean of the underlying Gaussian. The a3 parameter in the ZDD nomenclature adjusts the third moment or skew. Here the skew is altered by the width of the convolved half-Gaussian in the GMG.
This is also the ZDD used in the GenNLC[G] models. For the GenNLC[G] models, a0, a1, and a3 will be identical. The a2 width or second moment term will reflect a kinetic time constant. Please see the GenHVL and GenNLC equivalence topic for further details.
a0 = Area
a1 = Center (as mean of underlying Gaussian)
a2 = Width (as SD of underlying Gaussian)
a3 = Half-Gaussian convolution width
