Module plan 

Couplings of complete mode blocks, computed once and shared by every pair of positions, with the radial functions and harmonics evaluated once per displacement.

Upstream: treams.sw.translate, which evaluates one entry at a time; a plan gives the same coefficients for a whole block.

Structs

Term 🔒

One term of a block entry: weight times the harmonic table entry at index.

TranslationPlan 🔒

Geometry-independent spherical mode couplings, shared across position pairs.

Functions

degree 🔒

Position of degree p in a radial sequence.

degree_orders 🔒

The distinct degree-order pairs (l, m) of modes, in order of appearance.

harmonics 🔒

Harmonic (p, m) pairs of degrees p <= lmax in table order; (p, m) sits at p * p + p + m.
