D. Cohen summary of the HD93129A grating spectrum fitting focusing on taustar values and taking beta=0.7 to be the standard (but other parameters and other assumed beta are also discussed) Si XIV (6.18 A) taustar = 1.64 (0.38 - 3.44) {just slightly higher with beta=1 -- 1.95 w/ (0.58 - 4.22)} Si XIII (6.65 A for r) taustar = 0.81 (0.42 - 1.44) {slightly higher with beta=1 -- 1.01 w/ (0.52 - 1.63)} Mg XII (8.42 A) taustar = 1.03 (0.44 - 2.15) {slightly higher with beta=1 -- 1.35 w/ (0.61 - 2.77)} Mg XI (9.17 A for r) taustar = 2.84 (1.15 - 3.56) {slightly *lower* with beta=1 -- 1.97 w/ (0.91:4.37) though the upper confidence range does get higher with this beta} Ro values (for beta=0.7) Si XIV (6.18 A) 1.01 (1.01 - 1.53) {upper limit higher with beta=1} Si XIII (6.65 A for r) 1.37 (1.23 - 1.49) {for beta=1, 1.63 (1.47 - 1.83)} Mg XII (8.42 A) 1.44 (1.17 - 1.71) {for beta=1, 1.81 {1.34 - 2.21)} Mg XI (9.17 A for r) 1.20 (1.01 - 2.08) {for beta=1, 2.41 {1.01 - 3.71)}
