Caption: Figure 13.
Offsets between separately reported TRGB magnitudes. The shifts are defined as ﹩{\rm{\Delta }}{\mu }_{0}={m}_{{\rm{thin}}/{\rm{thick}}}-{m}_{{\rm{literature}}}﹩. Blue and green symbols denote the thin- and thick-slice measurements, respectively. The vertical dashed black line indicates zero offset, while the dotted blue and green lines show the mean shifts for the thin- and thick-slice approaches. These systematic shifts are partially driven by updates to the JWST pipeline and DOLPHOT.
