Notes. The values are the median of the last 1000 steps in the MCMC chains. Uncertainties are computed as the geometric mean of the 16th and 84th percentiles of the same MCMC samples.(⋆) For this case the FWHM was fixed to limit the degrees of freedom because of the low S/N. In the top table, for sources with two lines, each line corresponds to a velocity component.
