Components of field at location of bcal readout

[Elton Smith <elton@jlab.org>]

Hi Zisis,

I wanted to get back to you on the question of field components.

The components of the magnetic field, as well as the total, at the
location of the Bcal readout can be found in GlueX-doc-912. See in
particular Figs. 9 and 11. These components are based on the TOSCA model
which is being used in the reconstruction. Updated fields based on ANSIS
are not yet available, but the two calculations have been checked at the
level we need for this purpose. In the region of interest, the field is
mostly radial (i.e. perpendicular to the bcal module).

Cheers, Elton.
