The combined integral number counts for MEGA’s four MIRI filters, with individual pointings shown in gray and the number counts using all pointings shown in green. The number counts of the total field have error bars representing the Poisson uncertainties. As a comparison, the CEERS number counts from G. Yang et al. (2023) are shown as blue crosses, while SMILES number counts from M. A. Stone et al. (2024) are purple triangles. The dashed vertical line represents the 5σ image depth for the MEGA pointings, which are shown in Table 1.
