[yt-users] optimal resolution for frb

[John ZuHone]

Hi Jon,

I'm on the road but I have some suggestions for this that I will send as soon as I can.

Best,

John

One thing that bothers me about this is the need to specify the dimensions of the frb.  For some reason 800 x 800 seems to be preferred in the yt docs, but it seems to me that there are certain optimal dimensions that depend on the grid structure.  For example an frb that uses pixels the size of the smallest resolution element/cell or some integer multiple of that (of course less refined cells would be split into multiple pixels).  How would one find what that grid size would be?  I guess what I'd need to know is the dimensions of that most refined cell in the computational grid.  How does one access the grid structure information in a dataset?
