Simulated weak lensing maps (Vale & White, 2003)

This directory contains simulated weak lensing maps (the convergence and shear) derived from ray tracing through large N-body simulations of the formation and evolution of large-scale structure. In all cases the fields are 2x2 degrees, have been downsampled to 1024^2 pixels and assume that the sources lie at exactly z=1. We have simulated two cosmological models:

NameBoxOmMOmLhs8
A3000.30.70.71.0
B3000.30.70.70.8

where the box side is in Mpc/h. The simulations have 512^3 particles and a Plummer equivalent smoothing length of ~20kpc/h (fixed in comoving coordinates). The particles have equal masses M~1.7e10 Msun/h.

For each simulation we produced 10 semi-independent lensing maps using the multi-plane ray tracing algorithm [1]. The convergence map is contained in kappa_A.?.fits and kappa_B.?.fits for models A and B with ? a number in the range 0-9. Similarly the two shear components are contained in gamma_A.?.fits.
