Description

These are the data for reproducing the results of the publication titled "The Outer Stellar Mass of Massive Galaxies: A Simple Tracer of Halo Mass with Scatter Comparable to Richness and Reduced Projection Effects" by Song Huang et al. Please see the Python scripts and Jupyter notebooks provided in the jianbing repo for examples about how to use these data files. And please contact dr.guangtou@gmail.com if you have any questions about these data. ------------------------------------------------------------------------------------------------- Here is a brief description of all the files: Data from N-body simulation: mdpl2_halos_0.7333_reduced_logmvir_13.npy Basic information about the dark matter halos from MDPL2 simulation For scale factor = 0.7333 (or z~0.4). Only for halos with logMvir > 13.0. mdpl2_particles_0.7333_72m.npy Particle catalog of the a=0.7333 snapshot from MDPL2 This is a down-sampled version with 72 million particles. topn_theory_demo.pkl These are the data used to create the theoretical demo of the TopN test. It is used for making the figures in this notebook. Catalogs of Galaxies or Galaxy Clusters: camira_s16a_cluster_use_bsm.fits The HSC S16A CAMIRA cluster catalog. redmapper_hsc_s16a_cluster_bsm.fits The HSC S16A redMaPPer cluster catalog. redmapper_sdss_cluster_bsm.fits The SDSS DR8 redMaPPer clusters in the HSC S16A footprint. s16a_massive_logm_11.2.fits 0.2
