Table 2: Mode height and linewidth parameters for HD 49933, given by the Reference fits. Values are relevant to l=0. Data marked with filled circles indicate where at least six of the seven fitters agreed on the value of the parameter to within $1\sigma $. Details are given in those cases where disagreement was noted at >$1\sigma $. The mode heights are typically underestimated by about 5% due to the interpolation of the gaps.
