This directory contains one-dimensional probability density functions (p.d.f's) 
of the velocity and pressure fluctuations  (expresed in wall units) at all the 
heights and several Reynolds numbers. The pdf's are computed along a window 
centered at each of the different Reynolds numbers and spanning +/-(d99/2)


The files are written in binary (HDF5) and as MATLAB structures, saved as .mat

For instance, a HDF5 file contains:

-------------------------------------------------
Retau    Dataset {2}        : Karman number, Retau = utau*d99/nu, at the first and last point in x-direction.
Reth     Dataset {2}        : Reynolds number based on the momentum thickness.
re       Dataset {1}        : Inverse of the viscosity used in the code,
		              which defines the scaling in which the code works.  
utau     Dataset {1}        : Friction velocity in computational units.
		          
yd99     Dataset {456}      : Wall-normal grid in outer units, y/d99
ygp      Dataset {456}      : Wall-normal grid in inner units, y+      
mean     Dataset {456}      : Mean value of the variable as a function of Y, in + units.
rms      Dataset {456}      : Root mean squared value of the variable as a function of Y, in + units.

nbin     Dataset {1}	    : Total number of bins used to compute the pdf. 
bins     Dataset {456, 300} : For each height, range used to compute the pdf: (Mean-8*rms) < Var < (Mean+8*rms)
pdf      Dataset {456, 300} : Probability density function as a function of the height, in + units.
