HI Massimo, I think you will need to use FixedResolutionBuffer if you want to generate a 2D image. Matt's suggestion will give you all of the finest resolution data but you would have to do a bit of work to generate an image array. FixedResolutionBuffer actually does all of the necessary work behind the scenes. FixedResolutionBuffer will not resample (and in fact will oversample in derefined regions) if you specify an image buffer with a pixel scale finer than the resolution of your simulation.

Thank you for the infos, Matt.

It is still not totally clear to me what is the final resolution of the projected map (without doing FRB), in particular when I am using several AMR levels.

May you clarify that?

Thanks,
