Table 5: Suppose that a stellar population has an observed mass ratio distribution $f_{q,{\rm obs}}(q) =1$ for $q_{\rm min}< q \leq 1$. What is the pairing function and the generating mass distribution fq(q)? This table lists the exponent $\gamma _q$ of the generating mass distribution $f_q(q)\propto q^{\gamma _q}$ that is most compatible with the synthetic observations.
