As of P88 (01 October 2011), after the deployment of the CalSelector service, Service Mode science data are no longer released to Principal Investigators as data packages but are made available for download as raw data from file lists accessible via the User Portal.

Please check Science Archive Facility for more information.

Please note that an archive query may return a result for data that are actually not yet in the archive (and hence are currently unavailable for download). This is caused by the fact that

1. the information returned for queries is derived from FITS header information which is available very soon after the corresponding data file has been created, and
2. the ingestion of the data themselves into the archive can only be done after they are transferred to Garching (through the network ).

This latter process typically takes less than one hour for electronic file transfer under conditions of nominal network performance.

If a data request is made for data that appear in a query result but are not yet in the archive those files requested will not be available and the requester will be informed that they have N status ("Not available"). The request will be closed and the user should simply try again after waiting for an appropriate time.

Users are strongly encouraged to familiarise themselves with the policy regarding the proprietary time of the data, as oulined on http://archive.eso.org/cms/eso-data-access-policy.html.

Note that this new data delivery policy does not change in any way the rapid data release procedure used in certain cases (e.g. pre-imaging for spectroscopy).
