ESO Archive Frequently Asked Questions

General: Are all data from ESO Archive available worldwide?

As a rule, science data in ESO Archive are available to users worldwide as soon as data proprietary period has expired (typically: one year), while calibration files are available immediately. A limited number of special programmes may have non-standard proprietary periods or be restricted to users from ESO Member States.
