A catalogue of E(V-I) extinction values is presented for 3174 (LMC)
and 693 (SMC) fields within the Magellanic Clouds. The extinction
values were computed by determining the (V-I) colour difference of the
red clump from Optical Gravitational Microlensing Experiment (OGLE
III) observations in the V and I bands and theoretical values for
unreddend red clump colours.
