To assess changes to the measured parameters from one model fit to the next containing more data we compute the change in Information Content - a metric to define the increase in information you have with the new model. Higher number == more information gained with new model

Information content change for 13/14 planets in the study. Showing a gain in information when shorter wavelength data is included in the fit. The bottom panel shows the cloud parameters broken down into the four specific components.

We show that the inclusion of data below 0.6 microns (@nasawebb-mirror.bsky.social#exoplanets atmosphere and that near-IR data alone is a poor predictor of the UV/optical spectrum measurable by @NASAHubble - associated with☁️

Two exoplanet spectra with models fit by increasing the amount of data used by 0.1 micron increments. Demonstrating that near-IR data alone cannot predict the cloud properties accurately as the models do not fit the data.
