Synthetic spectrum created from the median sampler results for SSN 22 (red), with the normalised MUSE observations (blue), each observation shifted by the median RV sampler result for that observation. The red shading above and below the synthetic spectrum indicates the limit of all error bounds combined (as determined in the method described in Section 3.5), also including the largest error for RV of any observations. The shaded wavelength regions are not within the selected line regions detailed in Table 1 and so are not considered in the fitting process.
