Improving the timing accuracy for inspiral signals

Abstract : The timing of inspiral signals is usually done considering the time when the signal ends. Combined to the fact that searches are performed using banks of templates which do not match perfectly the parameters of a real signal, this leads to uncertainties in the timing, through the correlation between the mass parameters and the signal duration. Part of the correlation can be removed however, by considering the time when the signal reaches a reference frequency lower than the ending frequency. The poster would show how this can be used to improve the timing accuracy, which has a direct impact on the resolution that can be achieved on time of flight measurements in a network of interferometers such as the LSC-Virgo one. Using such a reference time could also be useful to cluster triggers across the template bank.
