Data Volume Table

The table below lists the sizes of the various data products in DR13.  Note that the total data volume is greater than 125 TB. A substantial fraction (~50%) of this is raw or intermediate data that is primarily of interest to experts.  If your institution requires most or all of this data you may email us at the helpdesk to contact a data transfer expert.

There are additional, small value-added catalogs that may not be listed here, due to the timing of their release.
