Table 2

Interpolation/extrapolation errors, as estimated by the difference in effective temperatures inferred from a coarser and incomplete grid of model spectra, relative to those inferred from a finer and complete grid of model spectra, in both cases using 1D non-LTE calculations on MARCS model atmospheres (see Sect. 4.2.3).

Star
	Hα	Hβ	Hγ
Sun	0	− 1	+ 1
Procyon	+ 41	+ 23	+ 10
HD 103095	+ 7	+ 6	+ 4
HD 84937	− 11	− 3	+ 1
HD 140283	− 17	− 3	0
HD 122563	+ 60	− 47	− 136

Notes. A positive value indicates that a higher effective temperature is inferred from the coarser and incomplete grid than from the finer and complete grid.
