Photometric data and associated SED fit for the symbiotic system Draco C1. Red symbols represent observed broadband fluxes from GALEX FUV at 0.15 μm to WISE W3 at 10 μm. The dark blue symbol represents the XMM X-ray measurement in the 0.2–0.5 keV band, corrected for extinction (the non-corrected measurement is the shown by the light blue symbol). The black curve is our Kurucz atmosphere fit to the red giant primary, and the dark blue curve is the extinction-corrected blackbody representing the white dwarf (the non-corrected version is light blue), scaled to match the XMM and GALEX broadband data. The full (extinction-corrected) XMM X-ray spectrum is shown in light gray symbols.
