how to download data for example asf-email-examples.sh?

[enyun]

 
hi all,
 
Happy new year!
 
I'm trying to use asf-email-examples.sh, but can't find how to download the 
sample training data.
I find these from readme, but not found the download link from that amazon page.
Do you know how to download the data from amazon?
 
Any help will be appreciated~
 
thanks,
enyun
