Fit to the SED of UCAC2 46706450. HST/COS, LAMOST (normalized to r-band magnitude),and APOGEE spectra are shown in gray. The model fluxes from the hot WD and the K-type subgiant are shown in light blue and green, respectively. The combined model flux is shown in red. The black dots indicate filter-averaged fluxes that were converted from observed magnitudes. Gray open circles indicate WISE fluxes for which the flux correction was not taken into account.
