LEVS
Type: Adverb  (Real array * 30)
Use:  LEVS is an array of up to 30 numbers which represent
      contour intervals.  The contour spacing is determined by
      PLEV (as a percentage of the peak intensity in an image)
      or by CLEV (as an intensity).  The elements in LEVS must
      be in ascending order since the first element smaller
      than the preceding element is the indication of the end
      of the array.  NOTE: the LEVS values do not have to be
      integers, but they will be displayed to an accuracy of
      5 digits (plus .) with 0, 1, 2, or 3 after the decimal
      depending on the value of LEVS.
Null Value: 0 * 30
      Null value assignment is -10,-9,-8,-7,-6,-5,-4,-3,-2,-1,
      1,2,3,4,5,6,7,8,9,10, 10*0.  It is most useful with the
      PLEV (Null assignment) of 10.
