Mock LISA Data Challenge 1B:

We report on our F-statistic search for white-dwarf binary signals in the Mock LISA Data Challenge 1B (MLDC1B) . We focus in particular on the improvements in our search pipeline since MLDC1, namely refinements in the search pipeline and the use of a more accurate detector response (rigid adiabatic approximation). The search method employs a hierarchical template-grid based exploration of the parameter space, using a cöıncidence step to distinguish between primary (“true”) and secondary maxima, followed by a final (multi-TDI) “zoom” stage to provide an accurate parameter estimation of the final candidates.
