Comparison of the measurements published in this paper and added to ADHI as W^CF to the ones published in the NIBLES_I and KLUN17 data releases, represented by W^published. The data obtained by the NIBLES_I and KLUN17 collaborations are represented by purple triangles and orange squares, respectively. The black dotted line represents the case when W^cf = W^published. Left: comparison of the raw line widths and . Right: comparison of the corrected line widths and . In both panels, we observe a significant offset of 11 km s⁻¹ for the NIBLES_I sample.
