11 MAY 2015 New line lists for B and for 10B and 11B. Telluric isotopic abundances are included so that the combined spectrum reproduces the natural B spectra 10B = 0.199, log10 -0.701 11B = 0.801, log10 -0.096 For astrophysical work the isotopic abundances must be determined. The doppler widths are significantly different. Mass 10B = 10.012937 Mass 11B = 11.009305 Filenames *050010* = 10B *050011* = 11B *0500*Z = B *0500 = 10B + 11B GFEMQ0500.ALL is the final result for use in spectrum synthesis.
