[Halla12_software] Magnet field maps and coordinate system

[Paul E. Reimer]

Hello,

I am about to generate a field map for SOLID based on

   1. CDF
   2. ZEUS
   3. BABAR (although this seems to no longer be an option but is good
      for comparison).

What are we using for the origin of our coordinate system (z=0)?  I'm
used to either using the target center or the upstream face of the
magnet as z=0, with the beam headed in the positive z direction, y being
up and x to "beam left" to form a right handed coordinate system.  I
know that this is a trivial question, but I want to make sure that we
are all on the same page here.

Paul
