Fixed array focal plane counter positions (from Franz)

countersnew.dat (10/2/08) based on Yang's Single magnet focal_plane_design.xls
tosca file: single_row_long_q_narrow_return_yoke.op3
190 counters: from Eg=3.0 to 11.7 GeV for E_beam=12.0 GeV
below Eg=9.0 GeV: 50% sampling of 60 MeV bites

coordinates: (xcen,zcen) for z=photon beam line, y=vertical up, x=away from spectrometer
origin at crystal position (goniometer)
scen=position on focal plane (zero at position (-678.410;0;3842.163mm))
rotation in xz plane by -9.71355 deg. wrt. x axis
