Description: The integral metric as a function. (Contributed by Thierry Arnoux, 13-Mar-2018.)

**Hypotheses**
Ref	Expression
sitmf.0	⊢ (𝜑 → 𝑊 ∈ Mnd)
sitmf.1	⊢ (𝜑 → 𝑊 ∈ ∞MetSp)
sitmf.2	⊢ (𝜑 → 𝑀 ∈ ∪ ran measures)

**Assertion**
Ref	Expression
sitmf	⊢ (𝜑 → (𝑊sitm𝑀):(dom (𝑊sitg𝑀) × dom (𝑊sitg𝑀))⟶(0[,]+∞))

Proof of Theorem sitmf Dummy variables 𝑓 𝑔 are mutually distinct and distinct from all other variables.
