Description
Supplementary material to DESI's publication "The DESI N-body Simulation Project II: Suppressing Sample Variance with Fast Simulations" to comply with the data management plan.
We collect all the data and code needed to produce the figures in the paper. The data set mainly consists of halo two-point correlation function (CF), power spectra (Pk) and bispectra (Bk) from the AbacusSummit and FastPM simulations. For Pk, we include results from the base cosmology (c000), the secondary cosmology c002 and c004, respectively. For Pk and CF, we separate results with different halo mass cut 10^11 and 10^13 Msun/h. We provide python jupyter notebooks for the plotting routines. The subfolder "output" in each directory contains all the necessary data for the plots.
