The RayGalGroupSims suite consists of a set of N-body simulations of different cosmological models, which have been specifically designed to generate high resolution halo catalogs in redshift-space (light-cone) taking into account for all observable relativistic effects to first order in the weak field approximation.
To date we have realized a first run for a LCDM scenario with parameters set to the WMAP-7 best-fit cosmological model. The simulation covers a (2625 Mpc/h)3 volume with Np=40963 particles. Full-sky light-cone data in the redshift range z~[0,0.5] are generated during the simulation run without the use of replica.
We also produce narrow light-cones.
An intermediate light-cone in the redshift range z~[0, 2] with a rotation of phi = 25deg and theta = 25deg, with a 50×50 deg² f.o.v
A deep light-cone in the redshift range z~[0, 10] with a rotation of phi = 17deg and theta = 25deg, with a 20×20 deg² f.o.v
Halos in the light-cone have been detected with pFoF. Their apparent position in the sky has been computed using a ray-tracing method to account for all relativistic effects (redshift & angular perturbations) at first order in the weak field approximation. These include: Doppler effect, gravitational distortions, transverse Doppler, Integrated Sachs-Wolfe & Rees-Sciama effect, weak lensing effects. The distortion matrix computed using a ray-bundle approach is also provided with the halo catalogs.

Technical details about the data format can be found in the README file included in the tarball. Information about the physical mechanisms and the numerical methods used in the generation of the light-cone data catalogs can be found in Breton et al. (2018).
Healpix maps:
These maps were produced using a ray-bundle method with an aperture of 1e-4 radians (details in Breton et al. 2018). The information for nside and redshift are found in the map names.
