Posteriors of the DM density for different fiducial values and mission sensitivities. The fiducial values are represented by vertical dashed lines of different colors. The posteriors belonging to the same run share the colours. Note that, for larger DM densities or lower Allan deviations the posteriors smoothly transition from a step function to a Gaussian. Our criterion for producing Eq. (10) is the presence of a clear Gaussian centered on the true value.
