Caveats
No source-specific caveats are recorded.
Infrared TRGB measurements using HST/WFC3-IR and Spitzer data show ~3–4% systematically shorter distances than optical-band TRGB, suggesting either an extinction-law mismatch or intrinsic I-band TRGB variability with metallicity not yet fully accounted for.
