The maximum degree and order is 180, suitable for a 1/4 degree map. The LDEM_64 product is the source of this model, followed by a Fourier transform of each line and numerical quadrature of the coefficients times Plm. The normalization commonly used in geophysics is employed, whereby the integral over the sphere of each harmonic squared is 4 pi. The spectral power of the current model is considerably higher than that of Clementine-based models such as the ULCN2005 beyond degree 30, owing chiefly to better sampling of surface topography by LOLA. The higher degrees are included mainly for spectral analysis, as the physical shape of the Moon is too rough at kilometer scales to be adequately modeled in terms of a truncated spherical harmonic expansion."
