How Much X-ray and Gamma-ray Data Are Coming In and Going Out of the HEASARC Archive Every Day?

Last Update: 2015 August 07

As of August 2015, the HEASARC's high-energy archive is growing about 29 Gigabytes (GB) every day, equivalent to 11 Terabytes (TB) every year.

HEASARC users are downloading about 300 GB/day of X-ray and gamma-ray data, equivalent to about 110 TB/year. This can be compared with the current 70 TB size of the entire HEASARC High-Energy Archive. Thus, in one year the HEASARC user community downloads a data volume 1.6 times the size of the archive.

For more detailed statistics, including a breakdown of the data holdings by mission, check out the HEASARC Usage Statistics webpage.
