    keyword=Double peaks from CH2 runs to determine central angle

    Figure 1 shows dp distribution of entire CH2 runs events. I fit a
    gaussian on H peak, the stat. error of mean value is less than 10^-5. C12
    peak is better. They are with the central hole cut.
    So at least from this point of view, the data taken is good enough.
