[yt-users] Boundary of the data container

[Nathan Goldbaum]

Hi Junhwan,

yt uses the location of the center of a cell when selecting cells for a
data object.  If the cell center is inside the boundary of your data
object, *all* of that cell gets counted towards the data object. If the
cell center is outside the data object boundary, *none* of that cell gets
counted towards the data object.

It looks like you asked a similar question back in 2012 - Matt's answers
should apply here as well:

Cheers,

Nathan
