Gravitational wave signal of models s11, s20, s20s, and s27

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.

Gravitational wave signal of models s11, s20, s20s, and s27

Of the four three-dimensional simulations, there are three non-exploding 3D models
(s11.2, s20, and s27; see [2] for details), and one exploding 3D model (s20s; see [3] for details).

For each model, the amplitudes are given for three observer directions.
The files labeled with '_pol.dat' and '_equ.dat' contain the
amplitudes as seen by an observer viewing the simulation from
the 'Equator' and 'Pole' direction defined in [1], respectively.
In short, the 'Equator' observer is situated along the x-axis of the
computational grid and the observer at the "Pole" is observing the
simulation along the z-axis of the computational grid.
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.

The amplitudes are sampled with a time resolution of about 0.5 ms, i.e. the corresponding
Nyquist frequency
is about 1000 Hz. Note that the amplitudes of
models s27 and s20s are contaminated by anti-aliasing effects at late
times; see [1] for more details.

Gravitational wave signal of models s27-2D and G27-2D

The amplitudes based on the two-dimensional simulations ([2] [4]) can be found in the following files:

gws27_2d.dat (See the top panel of figure 8 in [1])
gwg27_2d.dat (See the bottom panel of figure 8 in [1])


These two files consist of two columns each, the first column indicates the time after core bounce and
the second column gives the quantity A20_E2 (see equation 11 in [1]). The amplitude A20_E2 corresponds to
the signal an observer situated in the equatorial plane of the simulation grid would observe.
