Discrepancy in tidal deformability of GW170817 between the Advanced LIGO twin detectors

This paper investigates how the parameters of a binary-neutron-star merger, GW170817, are estimated by Advanced LIGO detectors, Hanford and Livingston. The detectors successfully derive mostly identical results for parameters that have been measured for binary black holes such as the mass and spin but show discrepancies in the binary tidal deformability.
