Red clump sample inspection. (a and b) Absolute magnitudes in G and K for the selected sample. The yellow curves use the 3D extinctions from Bayestar, while the blue curves are for zero extinction shown just for illustration of shift towards the correct literature value upon reddening correction. Panels c–f compare theRC distances to inverse parallax, while panels g and h show the error in distances as a function of d for the two methods. Beyond 5 kpc, RC distances become more reliable than inverse parallax.
