Hello,
I am having an issue with a FLASH simulation and AMR, using the OrthoSlice method. I am aware of the note at https://yt-project.org/doc/reference/api/yt.data_objects.selection_data_containers.html?highlight=orthoray#yt.data_objects.selection_data_containers.YTOrthoRay

but when I try to sort on the "t" field it is not found. Is that a derived field that should be constructed when yt loads the file, or is it the responsibility of the FLASH simulation to write the "t" field to file? 

Jupyter notebook:
http://paste.yt-project.org/show/243/

Input file:

Thank you,
-Stephen
