This directory contains 0.5% of random samples of  dark matter particles from the snapshots of the BigMD box (2.5Gpc/h) with 3840^3 particles.

The redshift_list.txt  file lists the relation between snapshot number and redshift.

The  files are  compressed with bzip2. Once they are uncompressed, the  format is very simple, just   plain ascii with 6 columns with the particle positions X Y Z in Mpc/h and the peculiar velocity components   VX VY VZ in km/s.

Due to the large size of the files, it is recommended to use pbzip2, the parallel  bzip2 compression  tool to uncompress the files.
