The FEROS spectrum of HD 161701

Identification labels:
Interval: 340.1-340.2 nm---->label: 637  25.01 39826  474

637: last 3 digits of wavelengths in nm  lambda=340.1637 nm
25.01 = Mn II  25=atomic number of the element (Mn), 01=charge (II)
39826=lower enrgy level in cm-1
474=per mil residual intensity of isolated line before broadening (rotational + instrumental)

The spectrum was observed on September 9, 2006 Archive filename: FEROS.2006-09-09T01:58:39.269.fits Modified julian date MJD=53987.0239895 Nominal resolving power R=48000. The composite spectrum was overimposed to the synthetic spectrum by shifting the observed wavelength scale by -0.836 km/sec. This radial velocity is given in the header of the fits file. The wavelength scale of B star spectrum was shifted by -131.5 km/sec (-1.98A at 4500 A) relative to that of the A star spectrum. Gonzalez et al. (2014): MJD=53987.0870, Phase=0.6519, RV_A=29.97+/-0.09, RV_B=-101.54+/-0.16 RED labels are for the A star BLACK labels are for the B star.
