Simulation treats DOM as a point source #12

Open jllanfranchi opened 6 years ago

jllanfranchi commented 6 years ago

For close-in bins, this can yield much lower light estimates for spatial bin / directional bin combinations that are slightly off-axis. This shows up in simple 2D simulations with no scattering, so should also be an issue for 3D tables close enough that scattering hasn't redirected the photons.

Something to consider bringing tables to their greatest-possible accuracy.

Note that some kind of radius-dependent amount of smoothing in the tables could also compensate for this (of course implementing a more realistic DOM retro light source would avoid such ad-hoc techniques).
