Hi Elizabeth,

Sorry it's not working... I _thought_ that Athena cylindrical was working, but we're  not testing it, so perhaps we broke it at some point. 

Is there any chance that you can post the dataset somewhere so we can have a look at it, like Dropbox or Google drive? Send me private mail at jzuhone at gmail.com if you don't want everyone to have it.

I'm headed to sleep but I will try to have a look at it tomorrow.

Best,

John
