BolshoiP – BDMV

Description

BDM halo catalogue for all available snapshots, using the standard overdensity criterion with 360*background density

The table data can be extracted using the query interface.

General information on BDM tables is also available at Tables – BDM.

Please cite this data set using the unique digital object identifier doi:10.17876/cosmosim/bolshoip/001.
