How does the new gflux do on other cross sections? Did it change by an order of magnitude- isn't that the factor we were off?
Can someone comment on this?

There are a few issues I still need to address, but after certain corrections (the trigger for example) I believe we will have good agreement with older results from CLAS/g1 and SAPHIR.
