@ervw12 what is the current status of this issue - could you contact @sbastrakov by other means (mail etc.)

@cbontoiu How did you solve your initial error? `ValueError: operands could not be broadcast together with ...` Regardining units: yes, that should be the y-py phase space. The unit for...

The momentum component is just a field that is a equivalent to the momentum components at this field location. A kind of binning over p_x for example.

Regarding the error: could you please state what the `np.shape()` and `dtype` of `ux` is. It looks like there is something going wrong inside the openPMD-viewer normalization. The error could...

I am not that familiar with Tracing in openPMD-viewer, but I assume you need to add `particleId` to your particle attributes as described [here](https://picongpu.readthedocs.io/en/latest/usage/workflows/tracerParticles.html?highlight=particleid#workflow) (for tracer particles).

@cbontoiu regarding question 5 from your previous round of questions: Fig 4 of this paper was not created with PIConGPU but was part of the second experiment performed at LMU...

@cbontoiu perfect! If you evaluate the phase space with [`numpy.histogram2d`](https://numpy.org/doc/stable/reference/generated/numpy.histogram2d.html) please keep in mind that: - the momentum from openPMD-api/PIConGPU is the momentum of the macro particles - not that...

What would you prefer @ComputationalRadiationPhysics/picongpu-developers?

@psychocoderHPC I will test this PR.

Very good point @berceanu. Since many PIC codes support lasers from any side, this might be a very useful addition to the openPMD standard.
