VERITAS

VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a ground-based gamma-ray instrument operating at the Fred Lawrence Whipple Observatory (FLWO) in southern Arizona, USA. It is an array of four 12m optical reflectors for gamma-ray astronomy in the GeV - TeV energy range. These imaging Cherenkov telescopes are deployed such that they have the highest sensitivity in the VHE energy band (50 GeV - 50 TeV), with maximum sensitivity from 100 GeV to 10 TeV. This VHE observatory effectively complements the NASA Fermi mission.

Software: 

We use ROOT for some of our analysis code but the data are stored in files that are in a VERITAS-specific format.

Status: 

In the VERITAS collaboration we give this topic some thought from time to time but it suffers from a lack of manpower.

Outlook: 

Also the problem is not a big one since we an2cipate the data set to be 500 TB at the end of data-taking and we'll reduce that to 50 TB with mild cuts for long-term storage.
