Notes. Columns 3−5 are the errors associated with the uncertainties on one of the individual atmospheric parameters. Column 6 is the total error associated with the uncertainties on the atmospheric parameters. Column 7 is the total error, adding in quadrature Col. 6 and the standard deviations listed in Table 4 for individual species.
