.nd file format: Keyword Lines

Keyword Lines

Keyword Lines are used to store data other than velocity, density and Q-factors. Keyword Lines are not allowed in the .nd format used by the TauP Toolkit (Cortwell et al., 1999). A file using Keyword Lines is thus not compatible to TauP.

In an .nd-file for the IASP91 model you might define

!name IASP91
!radius 6371
!year 1991

For the Moon Model by Nakamura (1983), the respective lines would be

!radius 1738
!year 1983
!name Nakamura83
