Left: center-of-mass estimates for the LMC. Right: same as the left, but for the SMC. The centers derived from our original RC samples are shown as red open circles. Completeness-corrected samples are indicated by black “C” markers, and incomplete samples by dark blue triangles. Literature estimates are overplotted for comparison: stellar kinematic centers (blue “K”) from Y. Choi et al. (2022; LMC) and A. E. Piatti (2021; SMC); photometric centers (maroon “P”) from R. P. van der Marel & M.-R. L. Cioni (2001; LMC) and M. L. Mateo (1998; SMC); H I kinematic centers (magenta “H”) from S. Kim et al. (1998; LMC) and S. Stanimirović et al. (2004; SMC); and—for the LMC—the H. Rathore et al. (2025) center (orange “R”) and the S. Vijayasree et al. (2025) center (purple “V”). Table 1 summarizes all center estimates.
