= - 30.3h^{-1} \, Mpc$; however the $z-\,$coordinate depends on the parameter $|a|$, and remarkably is sensible to this value as can be seen with the following two examples.

1.  First consider the case when $|a|$ is slightly lower than the maximum value allowed by (\[|a|-Max\]), say $|a|=1156h^{-1} 
    \, Mpc$. Then $z = \pm 15.5h^{-1} \, Mpc$.

2.  Second consider the symmetric case when $|a| = |b| = 
    1142h^{-1} \, Mpc$. In this case one has $z = \pm \, 91.0h^{-1} 
    \, Mpc$.

Note that the classes ${\mathcal{G}_3}-{\mathcal{G}_5}$ do not yield models with a fixed value of $y$; instead, both $y$ and $z$ depend on the parameter $|a|$. In Table \[Tb:Examples\] we show the values of $y$ and $z$ calculated from
