finding binding
boundThe anomalous metallicity-color-magnitude gradient observed in some nearby galaxies (e.g., age gradients in M31 disk) implies that spatially-resolved TRGB distance determination, rather than global mean distance, can vary by ±0.10 mag depending on which field is sampled, contributing ±3–5% uncertainty to galaxy distance.
