Should the Jacobi–Piñeiro weighting look like this?
wJP[x_,a_,b_]:=x^a (1-x)^b
Hi; I’m Juan Díaz, coauthor of the paper. With the convention used; the factor (1-x)^b has been considered as part of the integral measure and, as a consequence, not included on the weight. Along the whole code, the weight functions and measures only appear in the definition of the steady states. In the Jacobi–Piñeiro one, it can be checked that such factor (1-x)^b is actually there.
