Hi,

note that our target angle is now 45 (or 47?) degrees. If the numbers
that Nik reported in his summary were obtained with the same macro as
he showed in elog message #33258, 32 degrees were wrongly assumed.

If you use instead

> root show_deep_asym_all_47.C 13934-13941 13943-13950 13952-13953 \
> 13954-13959,

you get

> A_ed_V Point Asymmetries vs Q2 Sector L: 0.273406 +- 0.0571174
> A_ed_V Point Asymmetries vs Q2 Sector R: 0.313992 +- 0.0379546

which means that things remain *un*changed!

Regards,

Michael
