Repeatability of MRS signal during commissioning. Top: MRS spectro-photometric precision. The presence of the CO molecular band between 4.9-6 µm in the G star HD 159222 results in the ratio bending downward in that wavelength range. Bottom: MRS spectro-photometric repeatability evaluated by taking the ratio of the extracted signal of HD 159222, which was observed twice. The measurements were taken 7 days apart. Band 4long is not shown due to the very low S/N in the data.
