Fitting the NUV–NIR continuum of CVSO 109A. We show the HST and X-shooter spectra (black) along with the photospheric template (dark blue), which is scaled using optical veiling derived by X-shooter. The parameters of the best-fitting model (red solid line) are listed in Table 4. The best-fit model is a combination of the accretion shock model (consisting of the three columns with energy fluxes of 1 × 1010, 1 × 1011, and 1 × 1012 erg s−1 cm−2, each with filling factors shown in parentheses in the legend; cyan, sea-green, and brown solid lines, respectively) and the D’Alessio et al. Irradiated Accretion Disk (DIAD) model (consisting of the emission from the inner wall; dashed line). Emission lines and regions strongly affected by telluric absorption were excluded from the fit. The gaps in the NIR spectra are the telluric regions, which are omitted from the plot to improve the readability of the figure.
