Planck Legacy Archive (PLA)
The Planck Legacy Archive (PLA) contains all public products originating from the Planck mission. As of March 21st 2013, the PLA provides public data products from the first 15.5 months of Planck operations. It notably includes full-sky intensity maps at all nine Planck frequencies, maps of foregrounds components at high resolution, and the Cosmic Microwave Background fluctuations at unprecedented sensitivity and angular resolution. Angular power spectra and cosmological parameter grids are also provided, as well as the Planck Catalogue of Compact Sources and the Planck Sunyaev-Zel’dovich clusters catalogue. Many additional data sets are provided as well.
Three mechanisms are provided to access these products: (a) a simple web interface that lists available products and allows for direct download; (b) a Java module which allows to browse, search, inspect, select, and download the products; and (c) download links embedded in the explanatory documentation. All three can be accessed via the links below. Additional pages describe the history of updates to the PLA, and how the use of Planck data should be acknowledged.
Access to PLA
A web interface to frequently requested products is freely accessible via the
The full dataset can be searched, selected (including e.g. selection of map or catalogue subsets) and downloaded via the
The PLA interface also inter-operates with the astronomical catalogues served by the Centre de Donnees 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.
For advanced users: the PLA Inter-Operability subsystem (PLAIO) is a machine interface allowing users to have direct access to the contents of the PLA without invoking the Java client.
