我们研究的辐射的能量和线性动量发射到无穷远的迎面碰撞的二元黑洞，从休息开始在一个有限的初始分离，在极端的质量比（粒子）的限制。对于这些配置，我们确定的辐射，可能是由于初始的三个几何形状的选择。这表明，对于空穴从初始适当间距${L}_{0}g~ 7 M的演化，迎头碰撞的辐射能量和动量将不受该选择的支配。对于辐射量大几个数量级的非迎面轨道，计算对初始三种几何形状的选择可能更不敏感。
We study the radiation of energy and linear momentum emitted to infinity by the head-on collision of binary black holes, starting from rest at a finite initial separation, in the extreme mass ratio (particle) limit. For these configurations we identify the radiation that may be attributed to a choice of the initial three geometry. This identification suggests that for evolution of holes from initial proper separations ${L}_{0}g~7M,$ the radiated energy and momentum from head-on collisions will not be dominated by that choice. For non-head-on orbits, where the amount of radiation is orders of magnitude larger, computations may be even less sensitive to the choice of initial three geometry.
