Note: The explanation of the columns is as follows: N gives the number of lines used; $\log\epsilon$ is the absolute abundance derived $\log\epsilon = \log$(N(X)/N(H))+12; $\sigma_{\rm ltl}$ is the line-to-line scatter; and [el/H] is the abundance relative to the Sun. For the references of the solar abundances needed to calculate the [el/H] values: see Reyniers & Van Winckel (2007). The dust condensation temperatures are taken from Lodders (2003), and references therein. They are computed using a solar abundance mix at a pressure of 10-4 atm. The abundance table of MACHO 82.8405.15 can be found in Reyniers et al. (2007).
