Transvarse Mass Spectra (Mt - M0)

For the Fixed T0 , mt-m0 spectra has been fit by (1/2*pi*mt)d2N/dmtdy = A*exp(- mt/(T0/cosh(y))) , where T0 is the global temperature at which Mike Heffner obtained it from his proton, pion and helion confidence contours, A is the amplitude or the normalization factor.

For the Free T0 , mt-m0 spectra has been fit by (1/2*pi*mt)d2N/dmtdy = A*exp(- mt/T) , then T0 = T*cosh(y), A is the amplitude or the normalization factor.

Rapidity Spectra (dN/dy)

For the K+ and K- dndy plots, The red line represents the gaussian fit, while the blue line represents the longitudinal flow fit.
