Notes. All parameters were obtained with MADCUBA as described in Sect. 3.3.1. The numbers in parentheses are the uncertainties. The quantities without uncertainties (in parentheses) are fixed in the fit. (a) Both lines are strongly blended with nearby lines, some of which are from unidentified lines.
