+\section{Introduction}
 This document contains a preliminary version a the 
 Work Breakdown Structure (WBS), Package Breakdown Structure 
 (PBS) for Planck-HFI Level 2 data processing.
 
-The different packages are listed here. It should be noted that
-all packages should be compliant with the general software 
-architecture and use the services of the corresponding 
-support modules (\gph{428}). \\
+The Level 2 activity of the HFI Data Processing Centre (DPC) 
+is divided between the Paris-Orsay-Saclay Data Analysis Centre 
+(POSDAC) and the London Planck Analysis Centre (LPAC).
+POSDAC will run the Level 2 data processing pipeline and have overall 
+responsibility for the collaborative work involved in its 
+design and implementation. LPAC will a major role for in the 
+activities that iterate and overlap between Level 2 
+and Level 3 (for which the Cambridge Planck Analysis Centre, 
+CPAC, plays the role analogous to POSDAC at Level 2)
+
+\section{HFI L2 processing software packages}
+The Level 2 workpackages are listed below, with a numbering 
+scheme derived from that in the 
+{\it HFI Science Implementation Plan (SIP: draft of 19/11/99) }.
+All packages should be compliant with the general software architecture and use the services of the corresponding support modules (\gph{428}).
