Derived angular resolution of the Mastcam-Z cameras a function of zoom. IFOV is calculated from the pixel pitch and effective focal length. $Q$ is measured as the FWHM of the LSF calculated when determining the MTF for the R0/L0 filters. The green dashed line demonstrates the GSD of a single pixel, while the red dashed line demonstrates the GRD predicted by the diffraction limit. We find that for shorter focal lengths, the pixel pitch begins to dominate the effective resolution of the Mastcam-Z cameras (though still does not meet the criteria that $Q\ll 1$), while for longer focal lengths, system contributions become the limiting factor
