Whole-mantle P-wave isotropic and anisotropic tomography beneath Japan and adjacent regions

<p>Dear readers,</p> <p>A file named "Japan_ISO.dat" contains whole-mantle P-wave isotropic tompgraphy beneath Japan and surrounding regions.</p> <p>The data format is as follows:<br>1st column: depth (km) (F8.2)<br>2nd column: latitude (deg) (F8.2)<br>3rd column: longitude (deg) (F8.2)<br>4th column:&nbsp;dVp (%) (F8.2)<br>5th column: Ray hit count (I8)</p> <p>These are values on grid points used for tomographic inversion.</p> <p>A file named "Japan_AAN_iso.dat" contains isotropic component of whole-mantle P-wave azimuthal anisotropy (AAN) tompgraphy beneath Japan and surrounding regions.&nbsp;</p> <p>The data format is as follows:<br>1st column: depth (km) (F8.2)<br>2nd column: latitude (deg) (F8.2)<br>3rd column: longitude (deg) (F8.2)<br>4th column:&nbsp;dVp (%) (F8.2)<br>5th column: Ray hit count (I8)</p> <p>These are values on grid points used for tomographic inversion.</p> <p>A file named "Japan_AAN_ai.dat" contains anisotropic component of whole-mantle P-wave azimuthal anisotropy (AAN) tompgraphy beneath Japan and surrounding regions.&nbsp;</p> <p>The data format is as follows:<br>1st column: depth (km) (F10.3)<br>2nd column: latitude (deg) (F10.3)<br>3rd column: longitude (deg) (F10.3)<br>4th column: Anisotropic amplitude (%) (F10.3)<br>5th column: Fast velocity direction (deg) (F10.3)</p> <p>These values are obtained by interpolation from the values at surrounding anisotropic grid points used for tomographic inversion.</p> <p>We hope it is useful to you.</p> <p>Kind wishes,</p> <p>Genti Toyokuni &amp; Dapeng Zhao<br>Tohoku University, Japan<br>E-mail: toyokuni@tohoku.ac.jp</p> <p>Reference:<br>Toyokuni, G., Zhao, D., &amp; Takada, D.
