Dear Blasters,

since this morning, we've been having record-breaking figure-of-merit,
both in regard of intensity as well as polarization!

The intensity is about twice as much as on Tuesday:
Rate of events passing d(e,e'p)n cuts : 10.3163 events/C

Evaluating the vector and the tensor asymmetry of recent runs (2.3kC)
after yesterday's repair of the nozzle and the leak, for runs
14336-14340 14342-14349 14351-14358 14363 indicates an hPz of:

A_ed_V Point Asymmetries vs Q2 Sector L: 0.542941 +- 0.0682155 with
Chi^2/ndf of 13.1422/5
A_ed_V Point Asymmetries vs Q2 Sector R: 0.462164 +- 0.0461412 with
Chi^2/ndf of 3.40036/5

and a Pzz of:

Pzz Fitted from Parallel kine 0.677763+-0.118927 0.0110609
Pzz Fitted from Perpendicular kine 0.45129+-0.784769 0.00280581
Pzz Fitted from L/R difference 0.65151+-0.13897 0.00171694

Now let's keep on running like this in the most efficient way!

Regards,

Michael
