MAP_POWER

          MAP_POWER[2]     Integer

        Maximum  exponent  of  3  and  5 allowed in automatic guess of MAP_SIZE.
        MAP_SIZE is decomposed in 2^k 3^p 5^q, and p and q must be less or equal
        to MAP_POWER.

        Default is 0: MAP_SIZE is just a power of 2. A value of 1 allows approx-
        imation of any map size to 20 %, while a value of 2 allows 10 % approxi-
        mation.  Fast Fourier Transform are slightly slower with powers of 3 and
        5, but limiting the map size can gain a  lot  in  the  Cleaning  process
        (which can scale as MAP_SIZE^4).
