Resulting posterior distributions for our preliminary test that controls our implementation of CROCODILE using the same chemistry as input as our forward model, namely vertically constant abundances of H₂O and CO, and reduced random scatter. The orange posterior shows the results of the retrieval using only MRCCS data to test the implementation of the cross-correlation likelihood function, the blue posterior is for the regular framework using only LRSP, and the green posterior shows the result for the combination of MRCCS and LRSP data. The dashed red line shows the ground truth used as input.
