Extended Data Fig. 6

Lines show the stellar contamination produced by unocculted spots and faculae. Shaded regions indicate the 1σ uncertainty on the stellar contamination due to the uncertainty on spot- and faculae-covering fractions. a, The region around the 10,830-Å (air wavelength) helium triplet at the resolution of the PHOENIX spectra (resolving power, R = 500,000). (b) The full G102 wavelength range in 15-Å bins.
