LISA Pathfinder is an ESA space mission designed to test critical technologies for the joint ESA/NASA mission LISA (Laser Interferometer Space Antenna). The main mission goal of the LISA Technology Package (LTP) aboard LISA Pathfinder is the verification of free-fall between two test masses with an accuracy of about 3 × 10−14 m s−2 / √Hz [1+(f/3 mHz)2] in a measurement bandwidth (MBW) between 1 mHz and 30 mHz.
The data analysis of the LISA Technology Package (LTP) will comprise a series of discrete experiments, each focussing on a particular noise measurement or characterisation of the instrument in various operating modes. Each of these experiments must be analysed and planned in advance of the mission because the results of a given experiment will have an impact on those that follow. As such, a series of Mock Data Challenges (MDCs) will be developed and carried out with the aim of preparing the analysis tools and optimising the various planned analyses.
