Only in python 3.11+ do we see ``` tests/test_0692_fsspec_reading.py::test_open_fsspec_s3[FSSpecSource] FAILED [ 70%] ... E ValueError: not a ROOT file: first four bytes are b'\xec_wu' E in file s3://pivarski-princeton/pythia_ppZee_run17emb.picoDst.root ``` looking...

The problem is the signature of `fs.cat_file`. For the file ```python import fsspec fs, path = fsspec.url_to_fs("s3://pivarski-princeton/pythia_ppZee_run17emb.picoDst.root", anon=True) ``` If I create a file-object handle and read the first 4...

The defaults are in spirit similar to the CMSSW defaults, though the use case is certainly different. I was hoping to gain some experience in the wild how different these...

This is due to https://github.com/CoffeaTeam/fsspec-xrootd/issues/64

As an aside, you can do this with http as well: ```python url = "https://eoslhcb.cern.ch//eos/lhcb/user/c/cburr/test.root?xrd.wantprot=unix&authz=" + token fin = uproot.open(url, verify_ssl=False) fin.keys() ``` or equivalently, ```python fin = uproot.open(url, verify_ssl=False,...

Seems like the pandas conversion is trying to create a new type that pandas will eat, but messes up. Depending on the use case, it might be worth moving to...

Hey, can we use the recursively defined `IndexedArray` for the gen particle parents? :)

lol that's a BDT So the NanoAOD is a bottom-up rather than top-down: each entry in the list has a reference to the index of its parent entry. I played...

Another approach is to nest the ObjectArray inside a Table, e.g. ``` import awkward as ak jets = ak.Table( p4=TLorentzVectorArray.from_ptetaphim(pt, eta, phi, mass), iso=isolation_vec, ) ``` Then it should carry...
