[d2n-analysis-talk] BB nofield sieve/vertex

[posik at jlab.org]

Hi all,

  I have started working on the optics. Here I show the results for a no
field run that we took, run 1250.

  The no field run is done in order to define the position of the wire
chamber through data. Here I compare my results to the results that
Diana/Xin have found. The d2n_mp_xxxx are the plots that I made and the
d2n_xxxx are the comparison plots that were done by Diana/Xin (not sure
who made them). They seem to agree rather well with each other.
