Hybrid waveforms

The

RR gauges

The radiation reaction terms at 2.5PN and 3.5PN depends on 2 and 6 parameters, see e.g. IyerWill95. These arbitrary parameters represent the residual gauge freedom in the relative coordinate x=x1-x2 leaving the formulas for energy and angular momentum flux invariant. CBwaves and the code of the Columbia group use different gauges BT and DD. The DD gauge can be easily analyzed within CBwaves. With the appropriate coordinate transformation (applied at 2.5PN order in the figure below) we can change form one system to the other.
