Data Volume

L500-4320-A/B runs

These are pure DM-only simulations carried out with GADGET-4.

• Full particle dumps for redshifts: About 2.8 TB per dump, yielding 28 TB for the 10 full dumps.

• Group catalogues: Summed over the output dumps, we have ~2.0 x 10^10 subhalos and ~1.7 x 10^10 FOF halos, consuming 2.3 TB storage.

• Progenitor and descendant information linking subhalos in time amounts to 1.1 TB.

• Merger trees weigh in with 2.8 TB, and contain about 145.5 x 10^6 trees.

• All snapshots with the previously most-bound particles make up in total 3.7 TB. The fraction of particles with this property grows monotonously in time, and reaches ~3.2 x 10^9 (4.0% of the total particle number) by z=0.

• The lightcones contain a very significant amount of data, summing up to 392 TB in total.

  Cone Number	Lightcone Type	Redshift Range	Distance	Particle Number	Storage
  Cone 0	full sky	z = 0 - 0.4	~1090 Mpc/h	3.43 x 10^12	64.6 TB
  Cone 1	one octant	z = 0 - 1.5	~3050 Mpc/h	9.44 x 10^12	177.7 TB
  Cone 2	pencil beam, 10 deg^2	z = 0 - 5.0	~5390 Mpc/h	1.02 x 10^12	19.2 TB
  Cone 3	disk, 15.0 Mpc/h thick	z = 0 - 2.0	~3600 Mpc/h	3.94 x 10^11	7.41 TB
  Cone 4	full sky, most-bound only	z = 0 - 5.0	~5390 Mpc/h	6.54 x 10^12	123.1 TB

• The weak-lensing mass maps amount to 1.2 TB and use Nside = 12288.

Each of the two 4320^3 runs has hence created around 430 TB, with the full particle octant to z=1.5 and the full sky most-bound lightcone contributing 70% of this storage.
