frame4.dat............2D-PIV data at centerplane of tunnel from x/c approx 1.09 to x/c approx 1.31
                      at phases 0, 10, 20, ..., 350, 360 (360 is a repeat of 0)

The data given are:
    x/c      = x-location, normalized by hump chord (c=0.4200 m)
    y/c      = y-location, normalized by hump chord (c=0.4200 m)
    Umean    = mean x-component of velocity in m/s
    Vmean    = mean y-component of velocity in m/s
    Urms     = u_rms=u' in m/s
    Vrms     = v_rms=v' in m/s
    UV       = -u'v' in m^2/s^2
    Npoints  = how many "good" measurements were made at particular x,y location

Regarding the Phase, the time at which peak BLOWING velocity was measured OUT
of the slot corresponds to approximately Phase=170 deg.

Using a convergence analysis, a conservative estimate on the maximum error 
of the turbulence data is 16%.  Therefore, the turbulence data given
here should not be taken as absolute levels, but rather should be used to 
assist in qualitative evaluation of turbulence models.



The data files are all "Tecplot-format" (version 10).
For example, for:

 I=96, J=70, K=1, ZONETYPE=Ordered
 DATAPACKING=BLOCK

the data can be read from a given section via:

      idim=96
      jdim=70
      read(2,*) ((x(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((y(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((u(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((v(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((uprime(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((vprime(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((upvp(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((points(i,j),i=1,idim),j=1,jdim)
