Hey Guys, Quick question on off-axis slices: is the normal vector pointed into the page as you look at the slice, or out of the page? thanks! Munier -- Munier A. Salem // 845.489.6450

It's something of a free parameter, as unless you specify the "north" vector it is determines by taking two cross products. You can see how it's determined in the file yt/utilities/orientation.py . -Matt

Thanks Matt!
From the line:
*east_vector = np.cross(north_vector, normal_vector).ravel()* it seems the normal vector points out of the page (assuming East is to the right). On Fri, Jul 26, 2013 at 12:41 PM, Matthew Turk <matthewturk@gmail.com>wrote:

(also, assuming I specified the north vector) On Fri, Jul 26, 2013 at 12:48 PM, Munier Azzam Salem < msalem@astro.columbia.edu> wrote:
