I have managed to compute the original LDR coefficients (b1,b2,b3) with arbitrary precision. In particular, ADDA now contains them up to 35 significant digits (887a63c)
Several workarounds exist - https://github.com/adda-team/adda/wiki/FAQ#how-to-simulate-light-scattering-by-a-particle-which-shape-can-not-be-described-by-any-of-the-adda-predefined-shapes but we may still want to incorporate it inside the main ADDA code at some point.

This should probably be implemented after #275 . And this issue is simpler (less broad), but will be convenient also for radar community (to specify frequency in GHz).
This is especially important for rectangular dipoles, since using the default formulation (point dipoles) there is very far from optimal (for most practical cases).
