Notes.

(a)

Phases computed with T0 = 2458713.4254 (primary eclipse) and PS= 4.93181 d, from Table 1.

(b)

RVs calculated with respect to the laboratory wavelength λ0 = 6562.81 Å. Standard deviation of the several measurements (see text) of each line is given in parentheses.

(c)

RVs are before applying a heliocentric correction. This correction is RVcorr = + 12.9 km/s, obtained with IRAF.RVCOR.

(d)

S/N is the signal to noise ratio measured in the wavelength ranges λλ6544–6546.
