Re: Tracking tasks

[David Lawrence <davidl@jlab.org>]

Hi Elton,

    We could add a larger straw, but I'm wondering if that should wait 
for the next round of tests. I say that just because I already have a 
list of 6 different geometries to test and we don't currently have an 
XML definition of the large-straw geometry.

Regards,
-David
