Fig. 4


Probability density function (PDF) of initial masses of the companion star M2,ZAMS for the different synthesis population models in Table 4. The gray bar is a normalized histogram, and the different colored lines are normalized kernel density estimates for different weights found from Eq. (14)and shown in the inset of this figure, for individual factors j and for the total weight given as the product over all j times the time spent around the orbital period, which is the black line.
