class THaExtTarCor: public THaPhysicsModule, public THaTrackingModule


 Calculate corrections to the reconstructed momentum and out-of-plane
 angle that are due to a finite x position of the reaction point
 at the target.  Finite x-positions occur as the result of

 - beam position deviations and raster
 - spectrometer misalignment
 - targets extended along the beam (finite y_target positions)

 This module implements a simple first-order correction devised by
 Mark Jones. It is sufficient for most applications of the Hall A HRS

 Currently, only the Golden Track of the given spectrometer is corrected.
 (This restriction will be dropped once all vertex modules support
 multiple tracks.)
 The corrected quantities are available in global variables
 of this module:

   x:        Effective x_tg found by this routine (m)
   y:        y_tg (unchanged) (m)
   th:       TRANSPORT theta at target (rad)
   ph:       TRANSPORT phi (unchanged) (rad)
   dp:       delta
   p:        absolute momentum (GeV)
   px,py,pz: lab momentum vector components (GeV)
   ok:       data valid status flag (0/1)

 The following global variables are avalable:

   delta_p:  Size of momentum correction (GeV)
   delta_dp: Size of delta correction
   delta_th: Size of theta correction (rad)

Int_t ReadRunDatabase(const TDatime& date)
 Qeury the run database for the correction coefficients.
 Use reasonable defaults if not found.
 First try tags "<prefix>.theta_corr" and "<prefix>.delta_corr", then
 global names "theta_corr" and "delta_corr".
