Why is my modified Pol01 running in batch mode works for all polarized photon states except for left circularly polarized photons?

I am attempting to use Pol01 example to examine the angular distribution of initially polarized photons Compton scattering off G4_Si. I have had to include several lines of code in the SteppingAction.cc which will print out information like, for…

smoothing polarization covariance matrices

There are implementations for smoothing spin 2 quantities like the Stokes Q and U: an example is healpy's smoothing. Does a similar implementation exist for smoothing (via Gaussian convolution) a covariance matrix of polarization quantities? e.g.…

Is it possible to emulate a polarization filter during image processing, using C++ or OpenCV?

I've looked all over Stack and other sources, but I haven't seen any code that seems to successfully emulate what a polarization filter does, reducing glare. The application I want for this code won't allow for a physical filter, so I was wondering…

How to calculate the polarity of sentimental scores in sentiment analysis

I extracted the comments and calculated the sentimental score using the lexicon-based sentiment analysis (-negative ~ +positive). I was wondering if this is right to try to use min-max scaling to calculate the affective polarization score for each…

Rotate Thorlabs ELL14 rotation stage with polarizer and find the angle at which there is minimum power using a Thorlabs power meter

I am using a polarizer in ELL14 thorlabs rotation stage and PM16-122 Thorlabs power meter. I want to rotate the polarizer and find the precise angle at which there is minimum power. I have the code for rotation mount control and to read the power…

Does ```/gun/polarization 0. 0. -1.``` in histo.mac of the Pol01 example represent the photon spin?

On page 348 of the geant4 User’s guide and applications manual (refer to following link) http://ftp.tku.edu.tw/Linux/Gentoo/distfiles/BookForAppliDev-4.10.03.pdf it states that "Pol01 - interaction of polarized beam (e.g. circularly polarized…
