Gravitational wave signal of models
s9-FMD-L, s9-RbR-L, s20-FMD-L, s20-RbR-L,
s9-FMD-H, s9-RbR-H, s20-FMD-H, s20-RbR-H

Here you can find the gravitational wave amplitudes published in [1].
The gravitational wave amplitudes are from matter flow
only, i.e. the contribution of anisotropic neutrino emission is not included.

We provide the signals published in [1] and the underlying quadrupole moments.
The labeling convention is such that a model name is followed by three numbers indicating
the number of grid points in the radial, polar and azimuthal direction, respectively.
The label 320x040x080 corresponds to the model tag -L (low-resolution) in [1] and the label
640x080x160 correspond to the model marked -H (high-resolution) in [1]. Following the
resolution indicator, the transport scheme is marked by either -RbR (RbR+) or FMD (fully multi-dimensional).

The amplitudes are sampled with a time resolution of about 0.5 ms, i.e. the corresponding
Nyquist frequency
is about 1000 Hz.
Important: The time sampling is not uniform.

For each model, the amplitudes are given for two observer directions.
The files labeled with '_zaxis.dat' and '_xaxis.dat' contain the
amplitudes as seen by an observer viewing the simulation from
the z-axis and a-axis of the simulation grid, respectively.
Each file contains three columns. The first column gives the time since
core-bounce, in seconds. The second and third columns hold the
A_x and A_+ amplitudes, respectively. Time is given in seconds after core bounce.

Quadrupole Moments

The quadrupole moments used to compute A_+ and A_x (see [1]). They are given in the following order:
t, Qxx, Qyy, Qzz, Qxy, Qxz, Qyz. Here, Q is the second time derivative of the
quadrupole moment, and t is time, in seconds, after core bounce.
