This is somewhat related to #183 . Anyway, the next step is to understand what is the standard (or several standards) existing for file extensions. While it is clear that...

When implementing single-polarization calculation, quadratic quantities can also be calculated (4 quantities, similar to the Mueller matrix - see how it is done in DDSCAT - Section 26.6 of manual...

Recently, we stumbled upon an issue for certain Bessel beams with very small half-cone angles (e.g., CS', TEL, and TML beams of order 2), which are almost proportional to circularly-polarized...

With respect to #114, it should be reconsidered which of that is really important. Probably the most important is use of `configure` or `cmake`. /cc @alkichigin

Another potential issue is related to using Fortran on MacOS. Currently, [gcc from Homebrew](https://formulae.brew.sh/formula/gcc) includes gfortran but the `gcc` itself remains a symlink to `clang`. This is good for performance,...

Concerning different adda modes (`seq`, `mpi`, `ocl`) with different dependences. The preliminary idea is to have following packages (a -> b means a depends on b): * adda -> gcc,...

This is also related with Continuous Integration (CI) on GitHub. Probably the latter can be implemented independently, but it would be much easier if the packages are already available.
