Retrieval results normalized for HD 984 B. The KPIC data are plotted in black. The companion model retrieved using nested sampling and petitRADTRANS is plotted in blue, scaled using the retrieved α_p from our fit. The companion model does not include tellurics (i.e., we show the model before it was multiplied to the telluric response function) to focus on the molecular features, but tellurics are included in our fits. The stellar model used to model the speckle contribution is plotted in orange, scaled using the retrieved α_s from our fit. The full model (i.e., combination of the companion and speckle model) is shown in dashed green. The residuals between the KPIC data and our retrieved model are shown as the gray points to the bottom. The x-axis is restricted for clarity, and we focus on one order only instead of the full data range (between 2.29 and 2.49 μm).
