Lemma A.1.

Fix $\alpha\in N^{1}(X)$ any ample class. Then the following assertions are equivalent:

(1)

For any form $\theta$ such that $\{\theta\}=\alpha$ and any continuous function $f$ , the pair $(\theta,f)$ satisfies the orthogonality property.
(2)

For any form $\theta$ such that $\{\theta\}=\alpha$ and any model function $f$ , the pair $(\theta,f)$ satisfies the orthogonality property.
(3)

For any form $\theta$ such that $\{\theta\}=\alpha$ , the pair $(\theta,0)$ satisfies the orthogonality property.
