The notation of “CF” means the conformally-flat condition , and that of “M” denotes
the maximal slicing
.
The notation of “KS” means the Kerr–Schild metric. In this case, the extrinsic curvature
is also set to that derived from the Kerr–Schild metric.
The notation of “Co” means a corotating NS, and that of “Ir” denotes an irrotational NS.
The notation of “Pu” means the puncture approach, and that of “Ex” denotes the excision approach.
Because all the papers published so far employed the polytrope for the EOS, we do not include the
EOS in Table 1.

As found in Table 1, the surveyed parameter space is quite narrow, in particular for the EOS of the NS
and the BH spin; complete sequences with have not yet been derived, and moreover, BH-NS
binaries in quasi-equilibrium in which the BH spin takes a high value
or the BH spin and orbital
angular momentum vector misalign have not been studied yet. These are issues left for the future. For the
initial data of the merger simulation, a slightly wider parameter space has been employed. We will
summarize this in Section 3.1.1.
