Known bugs
Wrong factor on B coefficient (single coeff version) -----------------------------(Probably fixed in the "calculator object" versions!) Under Kristensson normalisation (with CS = -1), my code gives B(1,0,n,n)/B(1,0,n,-n) == -(2n)! at (x,y,z) = (x,0,0) (expected plus or minus 1). A-coefficients seem to behave correctly. BUT THE CSPHASE MIGHT BE WRONG ON BOTH SINGLE A AND B (TODO TEST)
Xu's antinormalisation
"Xu's antinormalisation" is broken (most likely in legendre.c and maybe also in qpms_types.h) – the plane wave test fails and the spherical wave reconstruction as well (but the translation coefficients match the Xu's tables).
Longitudinal waves
Plane wave decompositions gives wrong value on the longitudinal part. The implementation of the L coefficients OR the longitudinal waves is thus probably wrong.
Singular value asymmetry
Similar as the scattering result asymmetry, although not necessarily only in the y-direction?
Overflows etc.
Assertion failed in gaunt_xu for test_vswf_translations.c and high values of LMAX (LMAX=25)
Moreover, the non-normalized legendre functions that are used in translations.c are likely to overflow for even smaller values of l. Therefore TODO: modify translations.c in a way that uses normalised legendre functions everywhere.
