Comparison of the continuum level determined with the original sigma-clipping method (gray dots) and the corrected version (black crosses). In order to better show the differences between the two methods, the y-axis has been selected to show the continuum level determined with the mean. The right panel shows a zoom in of the central region. The black crosses appear clustered closer to the real continuum level, 50 K, compared to the gray dots.
