C     *==========================================================*
C     | SUBROUTINE PTRACERS_TURNOFF_IO
C     | o Turn off some of the ptracers output flags
C     *==========================================================*
C     | Used in adjoint simulation (and called after the first
C     |  forward sweep) to avoid writing output multiple times (if
C     |  recomputations and/or grdchk) with the same iter number.
