- SUBROUTINE TRSCSD(PC,RC,PD,RD,H,CH,IERR,SPU,DJ,DK)
-C
-C *** TRANSFORMS ERROR MATRIX
-C FROM SC VARIABLES (1/P,LAMBDA,PHI,YT,ZT)
-C TO VARIABLES (1/P,V',W',V,W)
-C
-C Authors: A. Haas and W. Wittek

-C
-C *** PC(3) 1/P,LAMBDA,PHI INPUT
-C PD(3) 1/P,V',W' OUTPUT
-C H(3) MAGNETIC FIELD INPUT
-C RC(15) ERROR MATRIX IN SC VARIABLES INPUT (TRIANGLE)
-C RD(15) ERROR MATRIX IN 1/P,V',W',V,W OUTPUT (TRIANGLE)
-C CH CHARGE OF PARTICLE INPUT
-C CHARGE AND MAGNETIC FIELD ARE NEEDED
-C FOR CORRELATION TERMS (V',YT),(V',ZT),(W',YT),(W',ZT)
-C THESE CORRELATION TERMS APPEAR BECAUSE RC IS ASSUMED
-C TO BE THE ERROR MATRIX FOR FIXED S (PATH LENGTH)
-C AND RD FOR FIXED U
-C DJ(3) UNIT VECTOR IN V-DIRECTION
-C DK(3) UNIT VECTOR IN W-DIRECTION OF DETECTOR SYSTEM
-C
-C IERR = 1 PARTICLE MOVES PERPENDICULAR TO U-AXIS
-C ( V',W' ARE NOT DEFINED )
-C SPU SIGN OF U-COMPONENT OF PARTICLE MOMENTUM OUTPUT
