Notes. Numbers in parentheses are formal errors from the Gaussian fits in units of the last decimal; (n) = narrow component, (b) = broad component, (e) = emission component, (a) = absorption component. The line temperatures in Col. 5 are in TA units and are relative to the SSB continuum values reported in Col. 6 which have a 1015% calibration uncertainty.
