 MEANING: Specifies LKJ decorrelation degrees of freedom for each SIGMA
 block
 CONTEXT: NM-TRAN Control Record

 USAGE:
 $SLKJDF 0 (default)
 $SLKJDF [value ... ]
 $SLKJDF [(value)[xn]] ...

 DISCUSSION:
 SLKJDF is an option of the $ESTIMATION record.  $SLKJDF is a  separate
 record  that  allows  the user to specify LKJ decorrelation degrees of
 freedom for each SIGMA block.

 SAMPLE:
 $SLKJDF 4.5 3.5 -2.0
 Where 4.5 degrees of freedom are specified for the first sigma  block,
 3.5  for  the second, and - 2.0 specifies 2 degrees of freedom for the
 third sigma block, but a user-defined definition of the standard devi-
 ations   of   the  diagonals  for  the  third  sigma  block.  Use  the
 SIGMA_STD_PRIORU.f90 file in the ..\source directory as a template  to
 modify the SIGMA_STD_PRIORU to provide the desired probability density
 function. Set $SUBR OTHER=SIGMA_STD_PRIORU.f90 to use the  user  modi-
 fied template (you may rename the file for organizational purposes).

 RECORD ORDER:

 Follows $SIGMA
