Description
The gravitational wave signal of coalescing massive binary black holes carries exquisite information on the physical parameters of the source. These long-living signals enable the estimate of the source parameters on flight, i.e. when the signal-to-noise-ratio is still rising and the uncertainties are narrowing down. For a set of binaries, we provide analytical fit to the running uncertainties of the sky localization, luminosity distance, chirp mass, and mass ratio as a function of their total mass, redshift and time to coalescence, one month to one hour prior to merging.
Our aim is at guiding observers to program in advance LISA protected observing periods, to alert astronomers for a potential electromagnetic counterpart detectable during the inspiral phase and in proximity of the merger, taking advantage of the knowledge of the intrinsic parameters at the source and its coalescence time.
