Sputtering time correlations with thickness and roughness of coatings.

Variables		Thickness			Roughness
Coatings		Nb	Ta	V	Nb	Ta	V
Time	Pearson correlation	0.917	0.998	0.963	−0.018	−0.137	0.183
	Sig. (2-tailed)	0.000	0.000	0.000	0.963	0.725	0.638
	N	9	9	9	9	9	9

indicates that the correlation is significant at the 0.01 level (2-tailed). The bold values indicate the presence of high positive correlations between coating thickness and sputtering times.
