Table 1.

Radial gradient of [O III]λ5007/Hβ and [Ne III]λ3869/[O II]λ3727 ratios, EW_Hβ, and metallicity for the three stacked samples.

Sample	Median redshift	% of galaxies	[O III]λ5007/Hβ	[Ne III]λ3869/[O II]λ3727	EW_Hβ	log(Z/Z_⊙)
			[1/pixel]	[1/pixel]	[Å/pixel]	[dex/pixel]
4 ≤ z < 10	5.5	63	0.024 ± 0.008	−0.083 ± 0.021	−23 ± 2	0.08 ± 0.05
4 ≤ z < 5.5	4.7	30	0.013 ± 0.014	−0.085 ± 0.030	−20 ± 2	0.07 ± 0.06
5.5 ≤ z < 10	6.0	33	0.023 ± 0.007	−0.120 ± 0.033	−35 ± 5	0.04 ± 0.05

Notes. The values reported in this table are the slope of the linear fit of the radial profiles shown in Fig. 4, Figs. 6, and 7. We recall that the pixel size is 0.1″, and that the conversion scales (kpc/″) used for each sample are 6.113 kpc/″, 6.614 kpc/″, and 5.832 kpc/″, respectively.
