| Internal extinction in the Magellanic Clouds. |
| Reddening values for 2,356,052 red clump (RC) stars in the LMC and 561813 in the SMC. These are created in the style of figure 4 from "The VMC Survey -- XL. Three-dimensional structure of the Small Magellanic Cloud as derived from red clump stars" paper, Tatton et al. 2021MNRAS.504.2983T. The values provided are in the form of colour excess E(Y-Ks), and can be converted to Av via E(Y-Ks)=0.2711xAv. The reddening values are available in two formats; the reddening value for the individual star and the mean for the 1000 nearest RC stars (referred to here as smoothed reddening).
