| Sumario: | The object of this communication is to discuss the spectrograms of this star, obtained at Bosque Alegre (Córdoba Observatory) between 1955 and 1959- There are 27 measurable spectra available, well distributed over the different phases.
In each plate 28 lines were measured, selected from those recommended by the Victoria observers, for the 30 and 50 A/mm dispersion, since our plate dispersion is 42 A/mm. If instead of these lines one measures those used by Stibbs, one gets a systematic difference of +1.2 km/sec. The mean probable error of our plates is of the order of 1.5 km/sec. |
