DESCRIPTION                    = "This file contains a digital,
1 x 1 degree resolution map of the Moon's topography relative to
a spheroid of radius 1738 km at the equator, with a flattening of
1/3234.93.  The data are interpolated from the filtered
observations by the 'blockmean and surface programs' of the GMT-
system of Wessel and Smith (EOS, Transactions American
Geophysical Union, v. 72, p. 441-446, 1991).  It is a 360 x 180
grid from 89.5 to -89.5 degrees latitude, and 0.5 to 359.5
degrees longitude.  No attempt has been made to provide data at
the poles (i.e. beyond about 78 degrees), since the numbers are
unconstrained."
