2.1. LIGO - Virgo Observation of GW170817

A time-frequency representation of the LIGO data containing GW170817 is shown in the bottom panel of Figure 2
The text with Figure 2 reads:
Bottom: the time-frequency map of GW170817 was obtained by coherently combining LIGO-Hanford and LIGO-Livingston data. All times here are referenced to the GW170817 trigger time T0GW.
When you compare the three Lightcurves with the time frequency map it is very difficult to claim that the source is a binary merger of 2 (neutron) stars.
