Brief_I/O

 
   VARIABLE  I/O  DESCRIPTION 
   --------  ---  -------------------------------------------------- 
   small      I   Limiting measure of small intervals. 
   window    I,O  Window to be filtered. 
 

Detailed_Input

 
   small       is the limiting measure of the small intervals to 
               be filtered. Intervals of measure less than or equal 
               to small are removed from the window. 

   window      on input, is a window containing zero or more 
               intervals.  window must be declared as a double precision 
               SpiceCell.
 

Detailed_Output

 
   window      on output, is the original window, after small 
               intervals have been removed. 
 

Parameters

 
   None. 
 

Exceptions

 
   1) If the input window does not have double precision type,
      the error SPICE(TYPEMISMATCH) is signaled.
 
   2) If small is less than or equal to zero, this routine has 
      no effect on the window.

Files

 
    None. 

Particulars

 
   This routine removes from the input window every interval with 
   measure less than or equal to the limiting measure (small). 
 

Examples

 
   Let window contain the intervals 

      [ 1, 3 ]  [ 7, 11 ]  [ 23, 27 ]  [ 29, 29 ] 

   Then the following series of calls 

      wnfltd_c (  0, &window );                (1) 
      wnfltd_c (  2, &window );                (2) 
      wnfltd_c (  3, &window );                (3) 

   produces the following series of windows 

      [ 1, 3 ]   [ 7, 11 ]  [ 23, 27 ]         (1) 
                 [ 7, 11 ]  [ 23, 27 ]         (2) 
                 [ 7, 11 ]  [ 23, 27 ]         (3)
