Analysis based on Dessart et al., Multidimensional Simulations of the Accretion-induced Collapse (AIC) of White Dwarfs to Neutron Stars, ApJ, 644, 1063 (2006).
The gravitational wave signature of the considered AIC models has been extensively discussed in C. D. Ott, PhD Thesis, Max-Planck-Institut für Gravitationsphysik and Universität Potsdam, 2006. The complete text may be obtained from Christian D. Ott (cott at as.arizona.edu). A comprehensive summary may be found here.
Below we provide gravitational wave signature data for the two considered AIC models. All files are gzip-compressed plain ASCII text files.

Note that owing to the non-periodicity of the signals, even periodic boundaries had to be assumed for the discrete Fourier transform. The spectra were cut at 1000 Hz and rescaled to correctly yield the total emitted energy. |
