Solar analogs in the 2600 to 3200 A regionNo criteria for the selection of solar analogs are found. At low dispersion, the spectra of 16 Cyg A, 16 Cyg B, 18 Sco and alpha Cen A look identical to each other and to sunlight reflected from Galilean satellites with the possible exception of Mg II lambda 2800 being stronger in the stars. The use of alpha Cen A or 16 Cyg B as solar substitutes for planetary photometry is expected to be far superior to using published solar irradiances.
