Optical to UV spectral energy distribution of SDSSJ1035. Shown are the two spectra obtained by the SDSS (black and red) plus SDSS photometry (black diamonds), Swift-UVOT photometry (black diamonds), GALEX FUV and NUV data (magenta diamonds), and the XMM-Newton OM observations obtained by us at orbital minimum and maximum (blue diamonds). Swift data obtained at the same epoch are connected with lines. The black solid line is a log g = 8.25, T_eff = 11 500 K DA WD model spectrum scaled to a distance of 209 pc. Flux units are 10⁻¹⁶ erg cm⁻² s⁻¹ Å⁻¹.
