Mean eclipse spectrum (black curve) of V902 Mon and a range of stellar spectra from Pickles (1998) for several values of visual extinction A_V. The telluric lines around 7600 Å have not been corrected in the V902 Mon spectrum, and the Hα line is very prominent. The large black points represent the maximum possible contamination due to the nearby faint star, based on its Pan-STARRS magnitudes in the r, i, z filters, and this contribution is included in the stellar spectra shown.
