    ##############################################

    Average beta versus rms beta-beating

    Random errors defocus!

    The effect gets worse for lower beta*

    Tunes help to remove the systematic offset but uncertainty is a big problem.

    ######################################

    Jaime, GUI

    some help is needed for input file prefix.

    K-mod GUI done. python Analysis being integrated (filename).

    quad K needs to be an input.

    ########################################

    Felix, Kmod and AC dipole DA

    K-mod python testing on-going.

    Great AC DA simulations but Some unexpected loss, emittance to be checked. 

    #########################################

    Ana, beta from amp, 

    Ballistic reanalyzed without useless BPM names. 100m error bars dissappeared.

    Systematic errors decreased a lot for beta from phase. Fit might not improve measurement.

    Using only the arcs for the average beta computation. Removing the previous bad BPMs 

    changes results.

    Horizontal apparent miscalibration dissapeared.

    IPAC

    Piotr needs to redistribute papers, Limitations go to Felix.
