; y is in the horizontal + towards small angles.
; z is along the central optics axis.
; In transport coordinates phi = hyptar = dy/dz and theta = hxptar = dx/dz
; but for unknown reasons the yp offset is named htheta_offset
; and the xp offset is named hphi_offset
; Do not to change these values, since these are the zero order
; CMOP matrix elements. If you do change then your hms sieve
; plots will be screwed up.
