subroutine mc_calo_recon (delta_p,delta_t,delta_phi,y_tgt,fry,delta_y,delta_z,drift_to_cal)
C+______________________________________________________________________________
!
! MC_CALO_RECON : Reconstruct target quantities from tracks.
!		   This subroutine is part of the MC_HMS program.
!
! Right-handed coordinates are assumed: X=down, Z=downstream, Y = (Z cross X)
!
! Inputs are from common block in track_*.inc (except for fry):
!  xs, ys, fry  are in cm.
!  dxdzs, dydzs are unitless slopes (we say "radians" to contrast to "mr").
