k-w SST freestream values for w

I want to know the freestream values of the blending function for 'w' in k-w SST.
I am trying to simulate the k-w SST for a two phase channel flow on MATLAB and I am having problems obtaining the accurate blending function values.
The blending function is as follows:
Where 'y' is the nearest distance to any surface,
sigma_w_2 is a closure coefficient
CD is the cross diffusion modification
The values of F_1 should be 1 for near wall (implying k-w is switched on) & 0 for freestream values (implying k-e is switched on. However, I am obtaining incorrect values for the function. After reading through the SST model Menter mentions about freestream values for 'w'. I do not know what these values are.
If anyone does please let me know.
