Detailed Description

Given \(\tau_0\) and \(\tau_2\) compute the mass ratio \(\eta.\).

Author: Sathyaprakash, B. S.

Description

Given \(\tau_0\) and \(\tau_2\) one can determine \(\eta\) by solving

\begin{equation} -\eta^{2/5} \tau_2 + A_2 \left ( \frac {\tau_0}{A_0} \right )^{3/5} \left (1 + B_2\eta \right ) = 0, \end{equation}

where \(A_0 = 5/[256 (\pi f_{s} )^{8/3}],\) \(A_2 = 3715 / [64512 (\pi f_s)^2],\) \(B_2 = 4620/3715.\) This function returns the LHS of the above equation in x for a given eta.

Algorithm

None.

Uses

None.

Notes

The void pointer} *p should point to a struct of type EtaTau02In :

{
void *p;
EtaTau02In q;
...
p = (void *) &q;
}
