This file describes the name convention and the order of the data
presented for the pressure and Laser-Doppler_Velocimeter (LDV)
measurements. First the LDV data, next the pressure data will be
discussed.
     The LDV data, are obtained by the Swept Spectrum Analyzer and Burst
Spectrum Analyzers. The uncertainty of the measured quantities are also
presented as part of the data.
     The files are named starting with " LDV " to denote the data
are obtained with LDV. The subsequent numbers show the stations the
data is taken. The extensions "TC", "FS", "NS", designate the different
coordinate systems in which the data is presented. TC, FS, NS stand for
the Tunnel coordinates , the Free-stream coordinates and for the Normal
stress coordinates, respectively.
     In the files, at the first 15 lines several parameters deduced
from the data and the parameters of the measurement conditions are
given. 16th line was left blank to separate the data from these
parameters.
     The data at each point of the profiles consist of the raw data
and the derived quantites from the raw data. First line for each y
location point in the profile contains:
y, U, V, W, U uncertainty, V uncertainty, W uncertainty, u^2, v^2,
w^2, uv, uw, vw, u' uncertainty, v' uncertainty, w' uncertainty,
uv uncertainty, uw uncertainty, vw uncertainty
     y location in each profile is given in inches. U, V, W, mean
velocity components and the uncertainties on these quantities are given
as nondimensionalized with the daily reference velocities. u^2, v^2, w^2,
uv, uw, vw Reynolds' stresses and the uncertainties on the shear stresses
only are nondimensionalized with the square of the reference velocities.
     Instead of defining the uncertainties for the normal stresses,
the uncertainties for the fluctuating velocities are given. The
uncertainties for the normal stresses can be found by using

     uncertainty of u^2 = [ ( sqrt(u^2) + u' uncertainty )**2 - (
sqrt(u^2) - u' uncertainty)**2 ] / 2

     The uncertainties of the fluctuating velocities are
nondimensionalized with the reference velocities.
     Second line of the data for the same y point give the N,
anisotropy constant, A1, Townsend's Structural Parameter, and also
the Flow angle, the Flow Gradient Angle and the Shear Stress Angle in
degrees.

      The pressure data contain the time mean static pressure data taken
with Scanivalve and an inclined manometer. The results are presented in
pressure coeeficient form. The 4 files are named as, "ON", "WALL", "FAR",
and "NOSE", to denote the measurements on the wing, on the wall where the
wing sits, on a line at z/t=3.17 (t=2.824 inches, maximum body thickness)
to see the blockage effect of the body, and detailed measurements close
to the nose of the body on the wall, respectively. The extension "CP" is
used to indicate that the data files are containing pressure data.
      In the files, in the first 7 lines some information about the flow
conditions of the measurements are given. Next lines contain the data in
x/t, y/t, z/t, Cp, order.
