The headings are given in the first four rows. The first row gives the total number of records; the second row gives the column number (e.g. col1, col2, ... ), and the third and forth give the name and unit of the varibles shown in the individual columns.
The following is one example.
number of records = 559402

## ##
Normalload = normal stress
Pf = fluid pressure
T = temperature
Displ = displacement
LPV = load point velocity
TauAB = summation of shear stress from the torque couples
Taucorr = shear stress after correction of seal friction
Mu = friction of coefficient
Mucorr = Mu determined from Taucorr
h = thickness measured from the Instron position
hlvdt = thickness measured from a local LVDT
Ec = elastic deformation of the apparatus
Vsam = sample slip velocity
Vload = load-point velocity
h/h0 = normal strain
strain = shear strain
Instrpos = position given by the Instron frame
LVDT = position indicated by the local LVDT
Tauseal = seal resistence
