Violin plot showing the distribution of S/N ratios output from simulated stacks as a function of the beam FWHM (i.e. angular resolution) of the LIM experiment while holding the pixelisation constant. We show a version where we hold the size of the spatial aperture constant as well as a version where we set the spatial aperture to the size that maximizes the S/N ratio of the stack. Violins are offset slightly in the x-axis for legibility.
