Gaia’s flux-limited completeness modeled as a sigmoid function, whose shape parameter α is derived from the slope of the faint-end LF falloff. We estimate the 50% completeness limits for Gaia in the LMC and SMC to be approximately ∼20.9 and ∼21.0 mag, respectively. The non-extinction-corrected G-band magnitude distributions for the RC stars selected in the LMC bar (black) and SMC center (red) are also shown, demonstrating that our RC selection remains more than 90% complete at these magnitudes.
