Spectral energy distribution ofHD 135344 A. The black line is the best-fit model spectrum and the colored markers are the photometric fluxes with horizontal error bars showing the FWHM of the filters. The top panel shows the filter profiles and the bottom panel the residuals relative to the measurement uncertainties. For clarity, every 15th wavelength of the Gaia XP spectrum is shown, whereas the full spectrum was used in the fit.
