9) DATA1=T0, T0 IS IN THE LORENTZ-INVARIANT PION CROSS-SECTIONS BY THE FORM, E*(DSIGMA/DMOM**3)=C*EXP(-T/T0) .
10) DATA-RATIO = THE PION-/PION+ RATIO OF THE SINGLE-PARTICLE INCLUSIVE SPECTRA AT 180 DEGREE.
11) DATA2 = THE RATIO OF THE PION LABORATORY KINETIC ENERGY TO THE MAXIMUM VALUE KINEMATICALLY ALLOWED FOR AN N-N COLLISION, ENERGY/(ENERGY-MAX(NN TO NNPION) ).
12) DATA3 = EXPONENT N, WHICH APPEARS AS E*(DSIGMA/DMOM**3)=C*(MASS)**N.
14) DATA4 = X, WHERE X IS THE RATIO OF PION MOMENTUM-CM/MOMENTUM-CM-MAX.
15) DATA5 = ENGY*(DSIGMA/DOMEGA/DMOM**3) UNIT5 = GEV*(MB/SR/(GEV/C)**3)
16) DATA6 = N, WHERE THE MEANING OF N IS GIVEN BY E*(DSIGMA/DMOM**3)=C*(1-X)**N.
