[yt-users] Creating a sphere based on enclosed mass

[John ZuHone]

Hi Daniel,

I should add to Cameron’s note here that this would be a very interesting addition to the code base, if you are interested in working on it and submitting it for inclusion in yt. Others should comment on the best place for it to go in the code. 

Best,

John Z
