Currently we use a formula involving roots for lambda and nu of clusters.
However sometimes it is nice to compute these for a cluster picture (+ leading coeff) without roots, which just comes from the depths alone (as in the definition).
We should fall back to the definition when we don't have root information so we can do example 12.6 in generality
(s=(****)_1/4 *)_0
leading coeff 1 should have $\lambda_R = 0$, $\lambda_s = 1/2$.
