Kinetic model — Linear deceleration function.

The deceleration function is defined as a linear function, $q(z) = q_0 + q_1 (z - z_1)$. The comoving distance in units of the Hubble radius today is

$$D_c(z) = \frac{1}{E} \int_{z_1}^{z} e^{q_1(z_1 - z^\prime)} \left(\frac{1+z^\prime}{1+z_1}\right)^{(1+z_1)q_1 - q_0 -1} \mathrm{d}z^\prime,$$ where E is the normalized Hubble function at $z_1$.

Functions

This function returns the difference of the normalized Hubble function computed at z1 and z2: $$ \Delta E(z) = \exp \int_{z_1}^{z_2} \frac{1 + q(z^\prime)}{1 + z^\prime} dz^\prime, $$ where $q(z) = q_0 + q_1 (z - z_1)$, being $q_0$ = q, $q_1$ = qp and $z_1$ = z1.
