Comparison between the magnitudes of the TRGB in the LMC (blue filled squares) and in the SMC (orange filled pentagons) in all the considered passbands measured with the MF algorithm (mag${}_{\mathit{MF}}^{\mathit{TRGB}}$) and those measured with the Sobel filter (mag${}_S^{\mathit{TRGB}}$) shown at the top. The thick grey line is the bisector of the panel. Lower panel shows the differences between the two values as a function of mag${}_{\mathit{MF}}^{\mathit{TRGB}}$. The mean and the standard deviation of the differences is also reported. The horizontal grey lines mark the mean and the ±1σ range about the mean.
