[Clas12_verystrange] pion acceptance as a fcn of theta and z resolution

[ziegler at jlab.org]

Hi,

We had a couple of questions at our last meeting.
Please see the attached plot from Sebastien P. which gives the +/- pi
acceptance as a function of angle.  The difference in acceptance
noticeably in the lower momentum range is due to bending angle.
The other question was regarding the z resolution from the Si Vertex
Tracker.  A value of ~ 1 mm for pT>~0.4 GeV is about right.

Veronique.
