At the present time, the PLA contains only the Planck Early Release Compact Source Catalogue (ERCSC).
The Planck Early Release Compact Source Catalogue
The ERCSC is a list of high reliability (>90%) sources, both Galactic and extragalactic, derived from the data acquired by Planck between August 13 2009 and June 6 2010. The ERCSC consists of:
- nine lists of sources, extracted independently from each of Planck's nine frequency channels.
- two lists extracted using multi-channel criteria:
- the Early Cold Cores catalogue (ECC), consists of galactic dense and cold cores, selected mainly on the basis of their temperature
- the Early Sunyaev-Zeldovich catalogue (ESZ), consists of galaxy clusters selected by the spectral signature of the Sunyaev-Zeldovich effect.
Releases: ERCSC 1.2, Jan 2011 (first release). ERCSC 1.3, Feb 2012 (incremental update). ERCSC 1.3.1, Feb 2012 (Documentation update & current version).

According to Planck rules, any observations of sources included in the ERCSC, acquired before release of the ERCSC, had to be made public together with it. Data in this category is either published in Planck Early results papers, or directly provided in this page. The available data in the latter category is:
