Adopted kernel scales and RMSEs.

	Kernel scale	Magnitude	Kernel Scale C1	Color1	Kernel Scale C2	Color2
T_eff	0.8	144.059	1.01	165.71	5.77	195.77
log ɡ	0.325	0.310	1.646	0.312	0.415	0.316
[Fe/H]	0.45	0.221	1.944	0.233	0.440	0.233

Notes. The “Magnitude” column lists the RMSE of using magnitudes as features, while the column of “Colori” is the mag(n – 1)–mag(n) color and “Color2”, presents the optimized mag1–mag(n) color. The ’Kernel Scale’ columns match the magnitudes, colori, and color2, respectively.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
