  In this paper, we describe the results of N-body simulation runs, which
include a cosmic string wake of tension $G\mu= 4 \times 10^{-8}$ on top of the
usual $\Lambda CDM$ fluctuations. To obtain a higher resolution of the wake in
the simulations compared to previous work, we insert the effects of the string
wake at a lower redshift and perform the simulations in a smaller volume. A
curvelet analysis of the wake and no-wake maps is applied, indicating that the
presence of a wake can be extracted at a three-sigma confidence level from maps
of the two-dimensional dark matter projection down to a redshift of $z=3$.
