$ADDDET group          (optional, if NPDET>0 in $GMCPT)
$REMDET group          (optional, if NPDET>0 in $GMCPT)
 
   These two groups add (or remove) determinants from the
reference list.  The first line in the group tells how many
determinants are contained in the group.
 
 $ADDDET/$REMDET
   2
   2002
   +-02
 $END
 
These two determinants would be generated if the $PDET list
was used with NEXCIT=2 (or higher), but this $REMDET would
remove them from the generated total reference CI.
