Physically reasonable stationary axisymmetric spacetimes can (under very mildtechnical conditions) be put into Boyer-Lindquist form. Unfortunately a metricpresented in Boyer-Lindquist form is not well-adapted to the "quasi-Cartesian"meta-material analysis we developed in our previous article on "bespokeanalogue spacetimes" (arXiv:1801.05549 [gr-qc]). In the current article wefirst focus specifically on spacetime metrics presented in Boyer-Lindquistform, and determine the equivalent meta-material susceptibility tensors in alaboratory setting. We then turn to analyzing generic stationary spacetimes,again determining the equivalent meta-material susceptibility tensors. Whilethe background laboratory metric is always taken to be Riemann-flat, we nowallow for arbitrary curvilinear coordinate systems. Finally, we reconsiderstatic spherically symmetric spacetimes, but now in general spherical polarrather than quasi-Cartesian coordinates. The article provides a set of generaltools for mimicking various interesting spacetimes by using non-trivialsusceptibility tensors in general laboratory settings.
