Characterisation and Data Analysis for the LISA Pathfinder Mission — •Martin Hewitson — AEI, Hannover, Germany

The LTP (LISA Technology Package) is the core part of the LISA Pathfinder mission. The main goals of the mission are to study the sources of any disturbances that perturb the motion of the freely-falling test masses from their geodesic trajectories and to test various technologies needed for LISA. The LTP experiment is designed as a sequence of experimental runs in which the performance of the instrument is studied and characterised under different operating conditions.

The software developed for the LTP Data Analysis is a comprehensive data analysis tool which uses an object-oriented approach to data analysis, allowing the user to design and run data analysis pipelines, either graphically or via scripts. The output objects of the analyses contain a full history of the processing that took place; this history tree can be inspected and used to rebuild the objects.

This talk summarises the main experiments of the LISA Pathfinder mission from the point of view of data analysis. In addition, the data analysis software infrastructure will be introduced, together with details of the various test campaigns that are being carried out in order to test the analysis procedures and tools.
