Caption: Figure 2.

Centroiding residuals as a function of source magnitude for 25 simulated CSST g-1 images with an exposure time of 150 s. The left and right panels show ΔX_PSF = X_PSF − X_ref and ΔY_PSF = Y_PSF − Y_ref, respectively, where X_PSF and Y_PSF are the centroid positions measured from PSF fitting, and X_ref and Y_ref are the corresponding simulated truth positions from the mock reference catalog. Gray points represent individual stars, while red solid lines with error bars indicate the mean offsets and the corresponding 1σ centroiding precision in 0.5 mag bins.
