DOIAbstract
International audienceIn a previous article [1], we have reported on the first subpicometer interferometer flown in space as part of ESA’s LISA Pathfinder mission, and have shown the residual sensor noise to be on the level of $32.0^{+2.4}_{-1.7}$ fm/$\sqrt{\textrm{Hz}}$. This review provides a deeper and more complete overview of the full system and its interferometric mission performance under varying operational conditions, allowing a much more detailed view on the noise model. We also include the optical measurements of rotations through differential wave front sensing (DWS), which reached a sensitivity of as good as 100 prad/$\sqrt{\textrm{Hz}}$. We present more evidence for the long-term stability of the interferometric performance an...
