Caption: Figure 5.
Relative flux calibration process for the VO feature around 746 nm. Top panel: GHOST spectrum of telluric standard star in black with the continuum fit shown in blue. Middle panel: PHOENIX synthetic spectrum with Teff = 10,000 K, ﹩\mathrm{log}g﹩ = 3.50, and [Fe/H] = −0.5 shown in black with the continuum fit shown in blue. Bottom panel: GHOST spectrum of NGTS-EB-8 shown in black prior to the relative flux calibration and shown in blue following the relative flux calibration.
