Retrieved values of ﹩{R}_{{\rm{P}}}/{R}_{\star }﹩ (black points) compared to an input value (red line) as a function of wavelength. The measured values deviate from the input ﹩{R}_{{\rm{P}}}/{R}_{\star }﹩ value more significantly when the bin is moved toward bluer wavelengths, which are closer to the spectral edge. The range of pixels covered here is from 100 to 600 in the dispersion direction.
