Comparison of the JH spectra of 51 Eri b using the literature 2MASS values against the new photometry measured in this study. The updated photometry increases the planet flux by ∼10% in J and ∼15% in the H band. The updated stellar photometry is used in the remainder of this study. However, the final stellar spectrum used to correct the planet spectrum does not depend on individual filter photometry, as in Macintosh et al. (2015) and shown in this plot, but is generated by modeling the full stellar SED prior to converting the planet spectra from contrast to flux units.
