Notes. T stands for the template transparency according to Baranne et al. (1979), that is, it represents the template t(λ) transmission weighted by the covered wavelength range (Δλ): T = 1∕Δλ ×∫Δλt(λ) dλ. N stands for the number of lines included in the template and σ stands for the template mean line width (in Å). The characteristics of the HARPS DRS G2 template considered over our green range (last line) are showed for comparison (see text).
