Correlation of separability index with other variables

	Correlation coefficient	p value greater than
Response peak	0.07	0.5
Modulation strength (orientation)	0.08	0.5
Modulation strength (direction)	−0.01	0.9
Modulation strength (disparity)	−0.02	0.8
Response variability	−0.08	0.4

This table shows for five distinct variables that could be related to the separability index the Spearman Rank correlation index and the corresponding p value (rounded down to the nearest decimal). As shown, none of the correlations are significant, suggesting that the separability index does not represent these other variables and instead is a true measure of separability.
