Table 1

Mean values of the differences ΔT for the full T17 sample as a function of [Fe/H].

[Fe/H]	± Δ [Fe/H]	⟨ΔT⟩ (K)	σ(ΔT) (K)
0.35	0.05	–35	24
0.25	0.05	–23	33
0.15	0.05	–21	31
0.05	0.05	–8	35
–0.05	0.05	–11	40
–0.15	0.05	–9	44
–0.25	0.05	–22	52
–0.35	0.05	–32	54
–0.45	0.05	–54	53
–0.60	0.10	–72	55

Notes. The mean values of ΔT (third column) are determined in [Fe/H] bins centred around the values given in the first column, and half-widths listed in the second column. The last column displays the 1σ dispersion around the mean ΔT.
