Should I apply a limit on the minimum number of particles to obtain average values from a particular region of the simulation (e.g. a radial bin in a temperature profile)?
Or should I just apply a scale limit based on the resolution of the simulation? (e.g. minim radial bin has 10kpc radius)
This question comes because I understand that the gas particles are in reality tracer particles, which already represent an average, so I wonder if such limit on the minimum number of particles to obtain average values is necessary.
Thank you very much in advance!

A general answer isn't possible, it depends on what you're doing. If you are ever binning, you (usually) want the bins to be large enough to contain many particles/cells, so that you get a reasonably (non-noisy) average.
