Caveats
No source-specific caveats are recorded.
The Red Clump (RC), a core helium-burning phase with stable absolute magnitude (M_I ≈ −0.2 to −0.5 depending on metallicity), offers an alternative distance indicator to TRGB with ~0.15 mag precision in the infrared, applicable to galaxies up to ~10 Mpc.
