[yt-users] Athena units

[John ZuHone]

Stephanie,

You can set it up like this:

pf = load("virgo_weak_mag.0054.vtk",
                 parameters={"TimeUnits":3.1557e13,
                                         "LengthUnits":3.0856e24,
                                         "DensityUnits":6.770424595218825e-27})

Sorry, this is a little-documented feature.

Best,

John
