SLICS: Home Documentation Products About Credits


Documentation



The SLICS (Scinet LIghtCone Simulations) are primarily designed to support cosmological analyses
based on combined probes involving weak gravitational lensing observations.

The simulation suite consists of more than 800 independent N-body simulations ran with CUBEP3M,
each post-processed into 100 sq.deg. light-cones, for which a number of observables are available.
These include mock weak lensing galaxy catalogues, spectroscopic galaxy surveys catalogues and
lensing maps reconstructed from the cosmological microwave background.

The different data products are described in detail in Paper 1 and Paper 2.

In addition to the data products described therein,
we also make available the mass maps, shear maps and dark matter halo catalogues upon request,
as well as some two-point function measurements such as dark matter power spectra,
cosmic shear power spectra and correlation functions, projected clustering and galaxy-galaxy lensing measurements.

README files are included in the download directory of each of these simulation products
and contain essential information about format and recommended usage.
