in particular
For the following data see * Physical Review Letters* ** 81**, 19, 4140:

For alpha=0.5, gamma=1.5, Re=160, upper branch solution
with nx=64, ny=41, nz=64.

Fortran order (i.e. do z, do y, do x).

x is streamwise, y is wall-normal and z spanwise.

Field is sampled
at x=0 to (nx-1) Lx/nx likewise for z.
Sampled * uniformly * from -1 to 1 (included) in y.
(this old data was computed using a Fourier expansion,
no need for Chebyshev for free-free boundary conditions
so all you need to work with this is a triply periodic code).

Example: To reproduce Fig. 4a in *Phys. Rev. Lett.* ** 81 ** using matlab:

>> load PCF.u.dat
>> u=reshape(PCF,64,41,64);
>> xzcut=reshape(u(:,21,:),64,64);
>> contourf(xzcut)
