Same as Fig. 2, but considering the dome-turbulence contribution. The black open squares represent the average IQ_MUSE across each field, as in Fig. 2. The black filled squares show the IQ broadening attributed solely to atmospheric turbulence (i.e., IQ_MUSE after quadratically subtracting the estimated dome-turbulence contribution at each λ). The blue solid line corresponds to the estimated dome-turbulence contribution, following a power-law dependence on wavelength with the γ-index indicated in the bottom right corner. The green line corresponds to the quadratic sum of the predicted atmospheric (purple line) and dome (blue line) turbulence blur, fitting the measured MUSE IQ.
