Thanks Ricardo and Ed! I personally am not a big 
fan of the Jones and Mann SH recon. It is based 
on so little. On the other hand, it is in the 
literature. So, I leave it up to you and Keith to 
decide - perhaps Eystein can weigh in too.

I do, however, think it would be really helpful 
to included the borehole data (see prev. emails) 
- either as a single SH curve, or (probably 
better) two regional curves (Australia and S. 
Africa). Is there a reason this is not a good 
idea? Can't complain about snow bias down there...

Thanks again - I look forward to seeing the next 
draft and figure - complete w/ borehole I hope.

thx, Peck
