Begining a is 0.0001 roughly, final a is 1. exactly and  number of elements is  1500 roughly
a,dlna/dtau_supercomoving/(H0/100),dplus, dlndplus/dlna
with tau_supercomoving integral of dt/a^2, dplus the linear growth rate (not normalized to 1 at z=0)

param_xxxxx.txt

h : hubble constant divided by 100 km/s/Mpc
omega_m: matter density
omega_b: baryon density (used to compute initial power spectrum)
omega_r: radiation density

ns: spectral index
sigma8: linear rms of density fluctuations at z=0 smoothed in sphere of 8 comoving Mpc/h

w: constant equation of state (for wcdm models)
alpha: slope of the potential (for quintessence models)

Linear matter power spectrum at z=0
k, P   with k wavenumber (h/Mpc) and P power spectrum (Mpc/h)^3

Begining a is 0.001 roughly, final a is 1. exactly and  number of elements is  1000 roughly
a,H/H0,tau_supercomoving*H0,tlookback*H0,tproper*H0
a = 1 at z = 0 (today), t and tau = 0 at z = 0,
a is the expansion factor, h the Hubble constant defined as hexp=1/a*da/dtau
tau the supercomoving conformal time (integral of dt/a^2), t the look-back time, tproper is integral of dt/a!  )
