Comparison of our distances (x-axis, kiloparsec) with literature values (y-axis, kiloparsec). Each panel shows a reference scale (CW21, GS21, F16, A22, BS23, and HJ24). The solid black line shows y = x, and the coloured lines represent orthogonal linear fits obtained with iterative 3σ rejection for each dataset. The grey points indicate the objects excluded (>3σ) from the final fit. The insets show the residual distributions with the mean (μ) and scatter (σ).
