Notes. The first column lists the HIPPARCOS number. The three faint solar analogues with atmospheric parameters compatible with those of the Sun within 1σ errors are highlighted in large bold numbers, and the other three within 2σ errors in small bold numbers. The brackets indicate stars with suspected significant reddening values (see Table 3). Column 2 gives the best T_eff obtained by the weighted average of the values in Cols. 3 and 4. Column 3 displays corrected by the equation given in Sect. 5.3. Column 4 displays from the photometriccalibrations of Casagrande et al. (2010) and the colours in Table 1. Columns 5–9 to are self-explanatory. Three candidates listed in Table 1 are not listed here (HIP 13964, HIP 24742 and HIP 69232) because we could not derive their atmospheric parameters from PCA; their values lie outside the valid range of our calibrations. ^(*) and T_eff from Hα agree for this candidate. These values are out of the PCA applicability range, and was found to be significantly hotter than and T_eff from Hα. No reddening was estimated for this candidate and we consider its atmospheric parameters as unreliable.
