Package bank

This is a module that generates a template bank to search for inspiralling and merging binaries consisting of neutron stars and/or black holes. Template placement is based on the geometrical formalism [5,3]. A user calls either LALInspiralCreateCoarseBank, to create a coarse bank, or LALInspiralCreateFineBank, to create a fine bank, at specified minimal matches. LALInspiralCreateCoarseBank first chooses templates along the $\eta=1/4$ curve and then systematically lays a rectangular grid in the $\tau_0$-$\tau_2$ plane, or $\tau_0$-$\tau_3$ plane depending on user's choice.

If the metric on a (two-dimensional) signal manifold characterised by parameters $(x_0,x_1)$ is $g_{ij}$ then the spacing between templates is given by

$$dx_0 = \sqrt{ \frac{2(1 -MM)}{g_{00}} }, dx_1 = \sqrt{ \frac{2(1 -MM)}{g_{11}} }.$$ (38.1)
