[Eg6_analysis] Checking the performance of the extracted drift speed corrections

[Nathan Baltzell]

Hi Mohammad,

Looks like you also picked up a region of phi that didn't even exist  
before (~2.2 rad)!

Is it correct that there is 60% increase even in the 1.2 GeV runs that  
were being used
for the previous calibrations?  I thought old and new drift speed were  
consistent there?

And can you tell me where these newly cooked 10 runs are?

Regards,
Nathan
