Hi all,
I am unable to access the derived fields written for Orion such as temperature, pressure, etc.
The definitions are these fields are located here: yt-x86_64/src/yt-hg/yt/frontends/orion/fields.py
This is the error that I get if I try to access temperature:
In [14]: mi,ma= dd.quantities["Extrema"]("Temperature")[0]
