Notes. Spectra A1-A9 correspond to the observations of Program ID 68.A-0106, spectra B1-B6 to Program ID 68.B-0115(A), respectively. The global shift reflects the velocity offsets to the common mean for each spectrum. Shift 1 to shift 4 represent the individual offsets for the four selected wavelength intervals.
