log(χ²) map for the Lyα line fit with three components (disk, halo 1, and halo 2). Here we vary only the dust optical depth of each outflowing halo: τ_Lyα1 and τ_Lyα2. While the intrinsic Lyα equivalent width is allowed to vary from 77 Å to 130 Å, all other physical parameters do not change (we use those listed in Table 7). A degeneracy is clearly seen (darkest zones), running diagonally for the lowest τ_Lyα1 values. The white area shows the range for τ_Lyα1 and τ_Lyα2 from which the strength of each line component (halos 1 and 2) are consistent with the one observed from the HST imaging (see Table 2): halo 1 and halo 2 contribute up to 56 % and 44% of the total Lyα flux and up to 11% and 12% of the total UV continuum flux, respectively.
