; Offset in the spectrometer momentum.

; The sdelta_offset,stheta_offset,sphi_offset effect the
; reconstructed target quantities. Used in s_targ_trans.f
; For transport x is in the dispersive direction with + down
; y is in the horizontal + towards large angles.
; z is along the central optics axis.
; In transport coordinates phi = syptar = dy/dz and theta = sxptar = dx/dz
; but for unknown reasons the yp offset is named stheta_offset
; and the xp offset is named sphi_offset
; Do not to change these values, since these are the zero order
; CMOP matrix elements. If you do change then your soss sieve
; plots will be screwed up.
