SUBROUTINE RDSRC_EQ(PROJNM, XMLAT0,XMLON0,XMLAT1,XMLON1,
; AZMOD, SRC,IERR)
!
! Reads source list for body waves and corrects back-azimuth.
! Now handles memory allocation within routine.
!
! If the model is striking east-west, (i.e., azmod = 0),
! then X is positive North, and Y is positive East. Hence if the
! back azimuth (baz) is 180 degrees the incoming wave will be
! advancing in the +X (pure north) direction. In general, the
! slowness vector (px, py, pz) will be:
! (sin(ai)cos(baz-pi), sin(ai)sin(baz-pi), cos(ai))/v
! The azimuth of the model is defined by the direction of the +X
! axis relative to north. Hence for a non-zero azmod we modify
! above form for (px,py,pz) to be
! (sin(ai)cos(baz-pi-azmod), sin(ai)sin(baz-pi-azmod), cos(ai))/v
! However, bazn has been corrected when read in
!
