Hi,
Here is the vertex distribution that was requested of me during the Friday
meeting. I included three different ways of obtaining the vertexes: using
TBTR bank, cut on cos theta in TBTR bank, and MVRT bank. Also you will see
the vertex distribution is for the test target used in November, the
silver target used til recently, the silver target emptied recently, and
then the new target installed within the last week (which I have dubbed
March New Target). If there are questions, concerns, or would like to see
the vertex in a different way, please let me know. I only picked some
histograms that seemed most relevant, but have more available.
