Notes. Identification names, coordinates and 2MASS JHK magnitudes from Negueruela et al. (2011) for Alicante 7 and Gonzalez-Fernandez & Negueruela (2012) for Alicante 10. Effective temperature (Teff) in units of Kelvin and microturbulence (ξ) in units of km s−1 from spectral synthesis of GIANO-B spectra. The EW of the DIB feature at λ1317.8 nm (vacuum) are in units of nanometers and heliocentric RVs in units of km s−1, also from the GIANO-B spectra. The derived AV extinction values from the DIB feature at λ1317.8 nm are based on the calibration with E(B − V) by Hamano et al. (2015, 2016) and are converted into AV by using R = 3.1. The LSR RVs were computed using the solar motion from Schönrich et al. (2010).
