All,

I know what these files ( P_is.jb and S_is.jb ) are, Jón Frímann created them based 
on a local Iceland travel-time model he found. Sorry it took so long to chime in. The 
"recent additions to the tables folder" rang a bell so I look at the file dates and 
then remembered Jón created these files for his location.

Regards,
Larry Cochrane
