Bridging the gap between LISA phasemeter raw data and astrophysical data analysis — •Yan Wang, Gerhard Heinzel, and Karsten Danzmann — AEI Hannover (Max-Planck-Institut für Gravitationsphysik), Leibniz Universität Hannover

LISA ( Laser Interferometer Space Antenna ) is intend to measure gravitational waves by using laser interferometry over astronomical distances. The input astrophysical LISA data are the TDI variables, which are combinations of time shifted phasemeter data and spacecraft distances that roughly synchronized to a common timescale. In practice, these raw phasemeter data are contaminated by the free-running local clocks. In this talk, I would talk about how and to what extent we could make the phasemeter raw data qualified for TDI combinations.
