Extended Data Fig. 2: Normalized residuals of the JExoRES and JexoPipe spectra relative to flat-line models.

From: Challenges in the detection of gases in exoplanet atmospheres

Extended Data Fig. 2

Histograms of normalized residuals, defined as ([data − model]/σ), for the JExoRES and JexoPipe reductions compared with their best-fit featureless spectra. Data represent single measurements per wavelength bin (n=1); bars show the frequency distribution of normalized residuals. The black curve indicates the standard Normal (Gaussian) distribution used for comparison.
