Figure 19: Numerical results for a BH binary inspiralling in a scalar-field gradient 
.
Left panel: dependence of the various components of the scalar radiation 
on
the extraction radius (top to bottom: 
to 
in equidistant steps). The dashed line
corresponds instead to 
at the largest extraction radius. This is the dominant
mode and corresponds to the fixed-gradient boundary condition, along the 
-direction, at large
distances. Right panel: time-derivative of the scalar field at the largest and smallest extraction radii,
rescaled by radius and shifted in time. Notice how the waveforms show a clean and typical merger
pattern, and that they overlap showing that the field scales to good approximation as
