c       For Barnes smoothing of parameters for tracking, e-folding
c       radius = retrk (km), influence radius = ritrk (km). Max radius 
c       for searching for the max vorticity = rads (km).  There is an 
c       important distinction between rads and ritrk.  rads is used to
c       determine the maximum distance from the guess position that 
c       we'll allow points to be in order to be considered as a 
c       candidate location for the updated fix position.  On the other
c       hand, ritrk is used once you're doing the barnes analysis on
c       data for that candidate location, so that if data is not within
c       distance ritrk of the candidate location, we ignore it.  Also, 
c       for use in find_maxmin, nhalf = the number of times to halve the
c       spacing of the search grid.  Note that different values are used
c       for the magnitude of the wind than for other parameters; this is
c       so that the search area is restricted in order to avoid a 
c       problem of the program finding one wind minimum near the center
c       and another one out near the storm's edge.
