sPHENIX EMCal discussion

    Hi Virginia,
     I have a couple of questions about the plots that I probably should know
    if I had attended all of the EMCal meetings.

    All plots show a fit result with a dp/p of 2% component. Is this just the
    momentum dispersion of the beam that has been incorporated into
    all fit results?

    For the plots on p. 3-9 the x axis of the plot on the left is labeled Input Energy
    and the x-axis on the plot on the right is labeled Energy. What is the difference
    between Input Energy and Energy?

     Is the Measured Energy in the y axis label on the left plots the same as the
    <E> in the formula on the y axis labels of the right plots?

    If I look at the plots on slides 4 and 5, I see that the UIUC 10deg and THP 10deg
    data points sit on top of each other everywhere except the 2, 3 and 4 GeV on
    the left plot. Is that because the width of the reconstructed energy distribution
    was different in the THP and UIUC modules for those beam energies? In some cases
    the THP points are above the UIUC points while in other cases they are below.
    Is there an explanation on how this could be? Thanks.

Hello all,

Attached are the latest versions of the EMCal plots for the test beam paper.  I've also included the linearity and resolution plots for the UIUC and THP data separately, though I believe we've decided the combined plots are best for the paper.  Comments are appreciated.

Best,

Virginia
