The coefficients are (defaults in parenthesis):
(-0.5) - Parameter (
) to calibrate impact of adverse pressure gradients for high 
regimes.
(-0.5) - Parameter (
) to calibrate impact of adverse pressure gradients for low 
regimes.
(0.6) - Parameter (
) to calibrate impact of favorable pressure gradients for high 
regimes.
(1.0) - Parameter (
) to calibrate impact of favorable pressure gradients for low 
regimes.
(1.0) -Parameter to scale the non-dimensional pressure gradient parameter
.
(1.06) - Parameter (
) to calibrate impact of 
for high 
regimes.
(2.25) - Parameter (
) to calibrate impact of 
for low 
regimes.
(1.0) - Critical Reynolds number correlation; built-in version or user-defined
via UDF. 
(1000.0) - Parameter (
) in correlation - specifies upper limit on transition location as
goes to zero.
(1000.0) - Parameter (
) - steers the switching function between high and low 
levels.
