a, dlna/dτs/(H0/100), D+, dlnD+/dlna
where a is the scale factor in the range 0.0001 < a < 1, τs is the superconformal time (= integral of dt/a2), D+ is the linear growth factor (normalized to 1 at z=0)

k, P(k)
where k is the wavenumber in units Mpc-1 h and P(k) the linear matter power spectrum at z = 0 in units (Mpc/h)3

a, H/H0, τs*H0, tlookback*H0, tproper*H0
where a is the scale factor, H is the Hubble rate defined as H = 1/a * da/dτs with τs being the superconformal time (= integral of dt/a2), tlookback is the look-back time and tproper is the proper time (= integral of dt/a)
