series method for half-space

ISO-D10F0.dat contains GFs for 4 types of point dislocations in a homogeneous half-space, for source depth being 10 km and field points on the surface, for fig.2.S10F0-Daab.grd means grid data for surface displacement in 'b' direction due to 'aa' dislocation for source depth being 10 km, for fig.4-6. ISO-D8F0-4000z-valid.dat and ISO-D48F0-4000z-valid.dat contain GFs of displacements for source depth being 8 and 48 km for isotropic case and R=4000km while TI-D8F0-4000z-valid.dat is same but for TI model and TI-D48F0-600z-valid.dat is for TI also but for R=600km.ISO-S08F0R5000.dat and ISO-S48F0R5000.dat contain DLNs similarlyTI-S08F0R4000.dat and TI-S48F0R600.dat are similarly for TI model.<br><br>

ISO-D10F0.dat 包含均匀半空间内4类点位错的格林函数（Green's Functions, GFs），适用于震源深度10 km、场点位于地表的场景，对应图2。S10F0-Daab.grd 表示震源深度10 km时，由"aa"型位错引发的、沿"b"方向的地表位移网格数据，对应图4至图6。ISO-D8F0-4000z-valid.dat 与ISO-D48F0-4000z-valid.dat 包含震源深度分别为8 km、48 km，各向同性工况下、R=4000 km时的位移格林函数；TI-D8F0-4000z-valid.dat 为上述数据集的横向各向同性（Transverse Isotropy, TI）模型版本；TI-D48F0-600z-valid.dat 同样适用于横向各向同性模型，但对应R=600 km的场景。

ISO-S08F0R5000.dat 与ISO-S48F0R5000.dat 同样包含DLNs；TI-S08F0R4000.dat 与TI-S48F0R600.dat 同理，对应横向各向同性模型。
