$DAMPGS group            (relevant if $DAMP was given)
 
   This is a free-format, line by line input group that
sets the initial values damping functions used to screen
the multipole expansion.  A check run may be helpful in
listing the names of the expansion points that are chosen
by MAKEFP jobs.  Very often the input group contains only
type -1- lines, and only in its second form.
 
----------------------------------------------------------
-1-        
    or    =
 
This line gives the name of the expansion point, and how
many terms are in the damping function (always 1 at
present).  The second form of this line lets you equate the
current point to some previous point's values in $DAMPGS,
skipping line -2-.
----------------------------------------------------------
-2-    
 
The linear coefficient (usually 1.0) and exponent of this
term in the damping function.  Repeat -2-  times.
If not given, the starting exponent for atoms is 2.0, and
for bond midpoints, 4.0.
 
----------------------------------------------------------
An example, for water, enforcing equivalent points, is:
 $dampgs                   or much more simply,
O1 1                 since the left is default exponents,
  1.0  2.0                     $dampgs
H2 1                          H3=H2
  1.0  2.0                    BO31=BO21
H3=H2                          $end
BO21 1
  1.0  4.0
BO31=BO21            The "BO" is short for bond midpoint.
 $end
