Identification labels:
Interval: 520.2-520.3 nm---->label: 256 26.00 34328 397
256: last 3 digits of wavelengths in nm lambda=520.2256 nm
26.00 = Fe I 26=atomic number of the element (Fe), 00=charge (I)
34328=lower enrgy level in cm-1
397=per mil residual intensity of isolated line before broadening (rotational + instrumental)
Spectroscopic Binary System SB2
Parameters of the A component:
Teff=12700K, log g=4.15 from Lanz et al., A&A 272, 465 (1993)
vsini=14.0 km/sec from our CRIRES spectra
Parameters of the B component:
Teff=9000K, logg=4.0 (guessed values)
vsini=5 km/sec from the CRIRES spectra
Luminosity: L(A)=80%, L(B)=20% (estimated from the Mass ratio derived from the
RV curves).
