Spherical harmonic model of the shape of Mars: MarsTopo719

THIS MODEL IS SUPERSEDED BY Spherical harmonic models of the shape of Mars MarsTopo719.shape is a spherical harmonic model of the shape of the planet Mars. This model makes use of 4-pi normalized spherical harmonic functions that exclude the Condon-Shortley phase factor of (-1)m. The description of how this spherical harmonic model was constructed can be found in Wieczorek (2015). MarsTopo719.shape is a truncated version of MarsTopo2600.shape.本模型已由《火星形状球谐模型》（Spherical harmonic models of the shape of Mars）替代。 MarsTopo719.shape 是火星形状的球谐模型。该模型采用了排除形如(-1)^m的康登-肖特利相位因子（Condon-Shortley phase factor）的4π归一化球谐函数（4-pi normalized spherical harmonic functions）。有关该球谐模型的构建细节，可参见Wieczorek（2015）的相关研究。MarsTopo719.shape 是MarsTopo2600.shape的截断版本。
