+Increasing values of the <em>dip</em> parameter progressively lower (or dip) the northern
half of the plane, and incline the southern half, assuming the <em>azimuth</em> parameter
is held constant at 0 degrees.

the center of the current region.

+<em>CELL</em> (integer) maps take less disk space than <em>FCELL</em>s (floating point),
