* Subroutine gprbi.f (DERIVED FROM read_B_inner routine from |
5 |
* tracker software analysis) |
6 |
* CALLED BY gpdat.F |
7 |
* |
8 |
* |
9 |
* it reads from rz files the two magnetic field maps taken inside the |
10 |
* spectrometer cavity and fills the variables in common_B_inner.f |
11 |
* |
12 |
* needs: |
13 |
* - .rz map files in containing coordinates of measured points, Bx, By |
14 |
* and Bz components + errors |
15 |
* |
16 |
* output variables: (see ....) |
17 |
* - px#(nx,3) with #=1,2 for the 2 maps |
18 |
* - py#(ny,3) |
19 |
* - pz#(nz,3) |
20 |
* - b#(nx,ny,nz,3) |
