Re: field map test and recrunch

Hi Mike,
   I finished lrs, it is the latest checked into cvs. I found some
errors in the calculation of charge on the order of 1-2%, which I will
explain in a future email. Also, there were some inconsistencies
between when data is recorded and when charge is counted, that I will
also explain. As it is now, there is still a very slight difference
between charge from lrs and lrn (both updated).
   I'll let Doug investigate the middle chamber offsets with straight
tracks.
   I am working on the T2D calibration, and making progress on it;
hopefully I will have something to show for the next collaboration
meeting. That's the same as wc_calib.
