CO absorption index: The CO absorption index defined in Eq. (2) is plotted for various sub-cloud CO abundances against the opacity of underlying cloud. The 30-ppmv curve has error bars estimated by applying \({\pm} 1 \sigma\) to both \(I_{2.26\,\upmu \mathrm{m}}\) and \(I_{2.32\,\upmu \mathrm{m}}\). It is found that these indices are stable up to cloud opacities ~30
