VSH_POL_DN_ALL_DP Subroutine

private subroutine VSH_POL_DN_ALL_DP(OUT, LMAX, THETA, PHI)

All standard-VSH members VSH_POL_DN for , from one VSH_CORE pass: . Zero for -- see VSH_POL_DN for the dipole-ratio caveat at .

Warning

Inherits ASSOC_LEGENDRE_NORM_ALL's -dependent stability limit (safe for unconditionally) -- see STABILITY_FINDINGS.md at the repo root.

1=, 2=, 3=; mode axis indexed by YLM_INDEX(l,m).
