Notes. A separate model was fit to the two temperature ranges. The coefficient a0 was fixed toits value for the 4000–8000 K temperature range. For the lower temperature range a0 was fixed to ensure continuity at 4000 K. The column labelled σ(BCG) lists the coefficients for a model of the uncertainty due to the scatter of log g.
