Fig. 4.

Light curves of the de-reddened monochromatic fluxes in the optical and UV light curves of Swift J0243.6+6124. From top to bottom: UVOT-uw2, UVOT-um2, UVOT-uw1, UVOT-u, UVOT-b, and Johnson V. Monochromatic fluxes have been dereddened with E(B − V) = 1.20 mag. The dashed gray lines represent the fits used to model the Be+circumstellar disk contribution (see Sect. 3.3).
