      SUBROUTINE SUCOV(CDCTL,KULOUT) 3,3
#if defined (DOC)

***s/r SUCOV  - Initializes the analysis Background term for the specific analysis configuration used.
*
*Author  : Luc Fillion - ARMA/EC - 6 Aug 2010 (from v_11_01B sucov.ftn. Refer to it for historic of upgrades).
*
*
*Revision:
*	   Ron McTaggart-Cowan - RPN - March 2012
*		- Add required arguments to subg_lam() and subg_glb()
*               - Use assumed-length declarations for string dummy args
!    -------------------
*
*Arguments
*     CDCTL   : 'I' --> identity is used for the correlation in spectral space
*     .         'H' --> homegeneous and isotropic error correlation
*               '0' --> return no statistics needed
