[yt-users] Particle profiles

[Matthew Turk]

Hi Elizabeth,

Here's a script that does it; you can get this with "yt_lodgeit.py
--download=1294".

http://paste.enzotools.org/show/1294/

Also, on re-reading your initial question, my initial suggestion of
adding a profile using "ParticleRadius" and "ParticleMassMsun" *will*
function, but it's not what you wanted.

Best,

Matt
