Optimization of Weak Lensing Lightcone Simulations for Higher-Order Statistics in the LSST era
Uniform discretization in scale factor and 2048^3 particle resolution allow reducing mass shells to ~50 and downsampling high-redshift particles with only 0.1-0.3 sigma impact on higher-order cosmic shear statistics under LSST-like conditions.
