[Halld-physics] [EXTERNAL] polarization orientations

[Michael Dugger]

Hi,

I am with Mark. The PARA and PERP orientations are from the past, where
PARA was parallel to the floor and PERP was perpendicular to the floor.
Internally it hardly matters, but to the outside world the PERP and PARA
designations used with 45/135 degree orientations will probably be
confusing. We just need the angles 0, 45, 90, 135.

Once the orientation is given in degree, the PARA and PERP designations
are superfluous.

Take care,
Michael
