Point Spread Function (PSF) calculation #266

PSF is to be calculated as in old RENATE, and a fast version is also to be implemented.

  1. A fast version can be done without the execution of the atomic physics calculation. The underlying observation is that the emissivity normalized to beam current is almost constant on the magnetic surfaces. Thus, for relative local smearing, a unit emissivity can be extended along the studied magnetic field line multiplied by the beam current profile. This then can be projected along LOS to get a good approximation of the PSF.
  2. A final version could take the exact 3D emissivity of the whole beam, just as RENATE does it. This will be way more expensive computationally but can be used to benchmark the first version for specific applications.
