Thanks for bringing this up. I would be curious to see how you are using `Particle` with Numba, and what are issues part from this `PDGID` to ìnt` conversion, at...

As you say @HDembinski , """ ... particle is not designed to process large arrays of PIDs ...",like "take an array of PIDs and give me a new array with...

@HDembinski, on your numba example below: for practical purposes would you not get a nice speedup using a case such as from cachetools import cached, LFUCache cacher = cached(cache=LFUCache(maxsize=64)) @cacher...

@henryiii, I will get to this soon. Where would you put such a template, say a file `TEMPLATE_UserDefinedParticles.fwf`?

This has been rather low priority but I should come back to it soon. For now let me add some info on how to create user-defined particles on the fly:...

Quick word to say that I'm working on a new "master data file" with structure in it as well. So this is not forgotten and in fact being dealt with.
