Tank Geometry

Here are few things I gathered about the tank geometry:

Dimensions:
Here is a drawing of the tank with some dimensions (and name of the variables) written

(NB there is an open office file here that could be extended)

Axis definitions:
Most of my info comes from: http://neutrino.phys.washington.edu/~superk/data/location.html

 "The Superk standard coordinate system has conventional right-handed
Cartesian coordinates with origin at the nominal center of the tank, +X
axis pointing toward String 1 of PMTs, and the -Y axis 42.5 deg west of
North."

Here are     a diagram of the tank with the axis realtive to north.
                a map of the mine (not great quality but ok if you zoom in).
               a superscan event display with th x and y axis drawn on the endcap.
