Magellanic Clouds Extinction Maps

An appendix to the paper:
'Absolute calibration of the reddening maps in the Magellanic Clouds'
by Górski et al. (2019)

Reddening maps with different resolutions and corresponding radii of fields are available to download for both Magellanic Clouds.
The E(B-V) is obtained from the (V-I) color measurement of the red clump, with the Cardelli et al. (1989) RV=3.1 reddening law parametrization.

The following columns in .txt files are as follows:
1 - Right Ascension [deg];
2 - Declination [deg];
3 - E(B-V) [mag];
4 - E(B-V) statistical error (based on the (V-I) color measurement uncertainty) [mag];
5 - sigma RC - width of the red clump (V-I) color [mag];
6 - N_RC - number of red clump stars [stars]

You may also take a look at histograms depicting statistical error of the reddening determination (σE(B-V)) and number of Red Clump stars (N*) in fields for each map:
