Calculate intermediate scattering function using a trajectory list.
isf_list <output file> <list name> <plane> <first wavenumber index> <last wavenumber index>
Options for <plane> are xyz, xy, xz, yz, x, y, and z. This chooses which dimensions in $k$-space to include in the calculation of the intermediate scattering function. xyz computes the full radial three dimensional isf, xy, yz, and xz calculate two-dimensional in-plane radial isf’s, and x, y, and z compute one-dimensional isf’s.
