In 3D codes, the photons location is generate on a triangle with an intent of having photon uniformly distributed it:
double w0 = UnifOpen(), w1 = UnifOpen(), w2 = UnifOpen();
phot->pos[0] = (w0 *…

If you set max_sigma high enough, flamedisx will give accurate results regardless of how bad the bounds estimation is. Empirically we found that max_sigma 5 is reasonable for our current bound estimat…

Currently, photons can't run on the head release of 21.1 in DAOD_PHYS because the corrections applied require show shape variables, and those are not present.
-
Mostly because there is no surface for photons to land on. Photon tracer will keep shooting photons and cannot reach a certain number of recorded photons.
-
We are making an error in the calculation of weights and T_r in estimators_simple, because we do not take into account the fact that we do generate photons over all wavelengths. Here is what we do

The conversion from wavefront to photons (or rays) has to be improved: The direction of photons must be calculated from the curvature of the wavefront, i.e. it stands normal to the wavefront. At the m…

If the [Energy Particles](http://picongpu.readthedocs.io/en/latest/usage/plugins/energyParticles.html#usage-plugins-energyparticles) plugin is activated for photons, one gets `nan` values after some p…

I observe that for some photons in MCTrack container, GetMass() and GetEnergy() return NAN. I suspect that this is due to rounding errors. In ShipStack.cxx, the FairRoot TParticles are converted to Sh…
