Analysis of the Conformally Flat Approximation for Binary Neutron Star Initial Conditions
Figure 3
Plot of the error in the central density versus the number of zones across the star. It is clear that there is only a 1% error with ≈15 zones across the star. Increasing the number of zones across the star so that there are >35 zones across the star produces less than a 0.1% error.
