Planck Legacy Archive (PLA)

The Planck Legacy Archive (PLA) contains all public products originating from the Planck mission.


The PLA interface also inter-operates with the astronomical catalogues served by the Centre de Données de  Strasbourg (CDS), via the interactive software Aladin. Data can be transferred seamlessly from the PLA to Aladin. Additional tabular data manipulation  functionality is available via the Topcat tool. Please note that users do not  need to install Aladin and Topcat a-priori in order to use them; they will be called up automatically by the PLA interface when  invoked.


If you experience problems using the archive interface, or have  questions related to Planck products, please submit a request via our helpdesk at
