Caveats
No source-specific caveats are recorded.
Absolute magnitude photometric calibration errors in standard passband systems (SDSS, Gaia, 2MASS) propagate into ±0.05–0.10 mag zeropoint offsets for TRGB, which alone can produce ~2.5–5% systematic H0 bias if not consistently applied across ladder rungs.
