These stars may have more precise distance estimates from spectrophotometry than from Gaia parallaxes beyond 3 kpc. However, RC stars have $T_{\\rm eff}$ and log g very similar to some red giant branch (RGB) stars. Especially for low-resolution spectroscopic studies where $T_{\\rm eff}$, log g, and [Fe/H] can only be estimated with limited precision, separating RC stars from RGB through established method can incur ~20% contamination.
