The IRAM data policy is as follows:

• IRAM archives raw and online calibrated data of the 30m telescope, and raw data of the interferometer on unlimited time scales.
• Header information of interferometric observations later than 1991 can be found at the CDS (Centre de Données astronomiques de Strasbourg):
  http://vizier.u-strasbg.fr/viz-bin/VizieR-3?-source=B/iram/pdbi
• Header information of 30-meter telescope observations later than September 2009 can be found at the CDS:
  http://vizier.u-strasbg.fr/viz-bin/VizieR-3?-source=B/iram/30m
• Data from all projects are stored in the IRAM Data Archive. Raw data are stored for the interferometer while the online calibrated data are archived for the 30-meter telescope. Programs are distinguished between normal programs and Large Programs.
• Data from Large Programs in calibrated format are publicly available after an 18 month proprietary period (counting from the end of the last semester of observations) and are accessible through the IRAM Large Program archive
• The data of normal projects can be requested after a three year proprietary period (again counting from the end of the last semester of observations). Multiple large scale requests are excluded.

IRAM does not provide support for data reduction of such retrieved data. Referencing of these data should follow the standard IRAM reference (see the Data publication policies) and in addition include at least one reference to publications of the PI team, or the PI name and program number in case the data have not yet been published.
